Units of measurement in 1s – accounting in pieces and packages
A situation often arises when a product is on… the enterprise receives it in boxes (rolls, etc.), and ships it to customers in pieces (meters); In order to reflect such operations in 1C, you need to create two (and possibly more) units of measurement for the item.
To do this, you need to open the nomenclature card through the “Main Menu” – “Nomenclature Directories” (double-click on it or click the “Change” button). This will open the item card:
The main difficulty when creating units of measurement is the need to indicate the conversion factor from the new unit of measurement to the base one.
Please note that postings in the quantity part for accounting and tax accounting are formed in the base unit of measurement.
For example, the base unit of measurement is set to “piece”, and there are also two more units of measurement “packaging” and “box”. The conversion factor for a box is set to 1000, which means that 1 box contains 1000 pieces. And for packaging the conversion factor is 100, i.e. one package contains 100 pieces. In this case, the 1C UPP program is able to freely count not only packages and boxes into pieces, but also packages into boxes; for this, it will calculate the ratio 1000/100 and receive the correct answer that one box contains 10 packages.
Thus, it is recommended to establish the base unit of measurement that will correspond to the minimum possible unit of measurement (or the unit in which balances will be recorded in accounting and tax accounting).
For example, for Paper Ballet it is convenient to select pieces as the base unit. You can change the base unit of measurement in the nomenclature card:
After you are convinced that the basic unit of measurement specified in the nomenclature is correct, you need to go to the “Units of Measurement” tab (it may not be completely visible). On the “Units of Measurement” tab there is a list of units of measurement for this item.
In order to add a new unit of measurement, you must use the “Add” button. A dialog for editing units of measurement will appear. In this dialog, you must select a unit of measurement according to the classifier. In the classifier that opens, select the unit of measurement that you want to add. After selecting the “By classifier” and “Name” fields will be filled in:
Because in this example, the base unit of measurement is set to “Pieces”, and the added unit of measurement is also “Pieces”, then the conversion factor from “Pieces” to “Pieces” will be equal to one. Therefore, in the “Contains (pieces)” field, you must set the unit.
After the unit of measurement has been set according to the classifier and the conversion factor has been set, the new unit of measurement must be saved by clicking on the “OK” button. A new unit of measurement will appear in the list:
The unit for storing balances is highlighted in bold (in this unit it will be possible to generate management reports, for example, “Goods in warehouses”).
Since in the example the base unit of measurement was changed from packages to pieces, it is necessary to edit the conversion factor for the “Packages” unit of measurement. To do this, you need to double-click on it with the mouse, or click the “Change” button. In the dialog that opens, in the “Contains (pieces)” field, you need to indicate the number of pieces in one package, this will be the conversion factor:
For example, the conversion factor is 100.
After finishing changing the units of measurement, the item card must be closed by clicking the “OK” button.
You can check how units of measurement work in any document, for example “Receipt of goods and services”. Let’s create a new document “Receipt of goods and services” and add to it an item for which two units of measurement are set:
If the unit of measurement is set to “pack”, then the coefficient takes on a value equal to 100. When changing the unit of measurement from packaging to pieces, the coefficient in the document will change its value to 1:
When posting a document, the quantity taken into account will be recalculated from the specified units of measurement into units of storage of balances. You can specify the required units of measurement in the “Goods in warehouses” report by clicking on the “Settings” button in the report indicators.
Example with the unit of measure “Boxes”:

Картонная жизнь; как в россии зарабатывают на макулатуре
Продавец пирожков Мухудзин поставил в свою палатку на «Кожуховской» новый холодильник. Коробку не выбросил. Вечером за ней придет Зафар.
Дворник Зафар любит макулатуру и Баргигулу, свою жену. Cardboard boxes from TVs, refrigerators and shoes remind Zafar of the beautiful life he dreams of creating for Barghigul and his six children.
When he takes another piece of cardboard, Zafar says, he thinks about the happiness of the people who bought themselves a sofa, plasma or stereo system. Zafar’s receiver, attached to the cart with tape, broadcasts an oriental melody.
Zafar was born in the Tajik town of Pyanj 38 years ago. His wife used to work in Moscow, together with him, in a tandoor shop. In the evenings they loved to go to the Moscow River and watch the sunset. But children began to be born too often, so Zafar decided to send Bargigulu home.
Zafar doesn’t miss home – work doesn’t let him get bored. Zafar also has “his bros” living nearby. The bros work as neighborhood janitors, salespeople, and loaders in local stores.
Janitor Zafar knows nothing about separate waste collection. It is enough for him to know that Anvar will give three rubles for a kilogram of cardboard
Zafar sometimes goes out with his bros to smoke a hookah or “get high on nasvay” (a tobacco mixture. — Ed.
) on the embankment. He tries to do this rarely, because “at that age, the head should be occupied with others.”
Every day Zafar’s head is filled with waste paper. He takes it from the bros from the stores and from the trash heap assigned to him. Each janitor has his own container at his place of work. On weekends, Zafar goes to a nearby industrial zone in a “five”, bought together with his brother Mukhudzin.
Zafar also collects scrap metal. It is more profitable to collect it, but there are more problems with it – it is heavy. Zafar earns pennies from cardboard, but from “all the tricks combined” he manages to earn as much as the utility workers pay him – about 15 thousand rubles. Total – 30 thousand rubles per month. He sends twenty thousand home.
Zafar knows nothing about separate waste collection; collecting cardboard for him is not very profitable, but it is the right thing to do. Zafar also doesn’t know that there are 17 types of waste paper in Russia. Procurement enterprises do not take everything. But it is enough for Zafar to know that Anwar will give three rubles for a kilogram of cardboard.
Cardboard business of Anton and Alexey
The buyers were exhausted from the unexpected heat in Moscow; there was no hiding in the hot Gazelle; the cardboard in the back stank. Everyone is waiting in line for their waste paper to be picked up at seven rubles per kilo. About fifty people – Kyrgyz, Tajiks, Uzbeks – are hiding in the shadows of their cars, smoking, laughing, talking in a mixture of oriental languages with a pinch of Russian obscenities. Someone is playing backgammon.
Industrial zone in the south of Moscow. Behind the fence begins the territory of the production and procurement plant (at the request of the heroes, we do not mention the name. – Ed.
). This is an important link on the path of waste paper from the trash heap to its next transformation into packaging. Here the waste paper is cleaned of tape and dirt, turned into 600 kg cubes and sent further.
The production capacity of the plant is three presses, costing 800 thousand dollars each. The presses are designed like this: a conveyor lifts the raw materials to the neck, the cardboard falls into it and is compressed. The output is a cube. The manager says that once at his previous place of work in such a cube, a man left for St. Petersburg. He fell drunk and was mixed with cardboard.
The cubes are taken to the warehouse. They are transported from the warehouse by trucks and freight trains – the plant has its own railway line. The carriages depart every day to Kazan, Perm and a dozen other Russian cities. There these cubes will be bought for eight rubles.
The suppliers will put the cardboard ruble in their pocket.
Ten percent of the goods are exported. As a rule, these are the types of waste paper that are not recycled in Russia. For example, India readily purchases coffee cups. Prices are higher abroad, and you can put two or three rubles in your pocket.
Recycled cardboard is pressed into a dense cube. The manager says that once a man went to St. Petersburg in such a cube. A drunk fell into a neck and was mixed with cardboard
Moscow is the largest supplier of waste paper in the country. “In total, in Russia,” says the manager of the plant, “about 300 thousand tons of such cubes are produced per month. The plant makes 25 thousand.”
This is one of the largest procurement enterprises in Europe. It employs 300 people.
There is incomparably more waste. According to the association of paper producers, out of 15 million tons of paper waste per year, only 3 million tons are collected and sent for recycling.
Managers of the procurement plant Anton and Alexey are sitting in a small room. They are not in a good mood. The government has decided to introduce a duty of 43% on the export of waste paper. Their enterprise and 50 other procurement companies under the auspices of the Secondary Resources Association asked the president not to do this. This will kill their already not very profitable business.
In 2022, exports were closed as an experiment for several months. As a result, according to Anton, 30% of enterprises went bankrupt. Anton and Alexey believe that in this way the processing plants want to create competition among producers and lower prices.
According to Alexey, the introduction of customs duties leads to monopolization of the market for recyclable materials, because with such a duty, producers will stop trading for export. Alexey calls plants monopolists, which, if a duty is introduced, will be able to control prices for waste paper.
The waste paper business is capricious. Zafar will not collect cardboard for less than three rubles. If processing plants lower prices, no one will go to the collectors – collectors and processors will have to retrain to collect other waste. And 45 processing plants throughout Russia can cope without them.
Waste paper processing plants will make money from falling prices, and the company where Anton and Alexey work will go bankrupt.
Cardboard resuscitator Sysolyatin
Several years ago, a rubber woman arrived at the cardboard and paper mill in Kashira with waste paper. They tried to inflate her, but the woman only shook and let out air. The workers laughed.
This is a typical self-assembly: products of procurement enterprises. They don’t like self-collection at the plant, because along with such waste paper comes a lot of garbage that has to be cleaned out – otherwise a piece of iron could simply break the press.
Therefore, the mill prefers its own waste paper rather than imported one. Out of ten boxes produced by KBK, we get nine.
The plant is the final link in the journey of each cardboard. A place where waste paper is first broken down into fibers and then these fibers are recombined. It turns out new cardboard.
Work here works like this. Cubes come to the plant. Workers carefully inspect them, then feed them onto the conveyor. The conveyor takes the cubes for cleaning. Waste paper ends up in stinking industrial water with sand, breaks down into fibers and moves onto a conveyor.
The cleaned mass is wound on a special shaft with a diameter of one and a half meters. It spins and the paper pulp turns into cardboard. To do this, the future cardboard passes through several rolls, separated by presses, which squeeze out excess moisture from it. After drying, 50% moisture becomes 8%.
They don’t like self-collection at the plant, because along with such waste paper comes a lot of garbage that has to be cleaned out – otherwise some piece of iron could break the press
After this, the cardboard becomes packaging again and goes to factories where they will put something in it. Someone will buy a TV, a refrigerator or cookies. The cardboard will go back to landfill. If you’re lucky, he’ll come back again. If not, it will remain at the landfill. Now, according to the association of procurers “Recycled Resources”, cardboard worth a total of 900 billion rubles is buried in Russia every year. There is no one to collect it.
There are very few employees in the six-meter rectangular workshop. A couple of repairmen are in blue overalls, two female technologists are in green. The bosses wear gray overalls, but Sergei Sysolyatin, production manager, prefers a suit.
He worked in the steel industry for half his life. He was the head of a workshop, with six hundred people subordinate to him. In 1997, the plant collapsed, and a former classmate, with whom Sysolyatin played football, invited him to make cardboard from waste paper. Now he has thirty people under his command.
He loves his job, but he has a lot of problems. According to him, the local state district power station is doing nonsense – promising to turn off the water supply, because they themselves do not have enough water. The cardboard they bring is bad, but no one cares about recycling. Sysolyatin does not separate garbage waste because there are no bins for separate collection in Kashira. Just like throughout Russia.
Zafar and millions of other waste paper collectors continue to separate waste at a price of three rubles per kilogram. Yesterday my wife called, Zafar will soon have a son. We need to work harder.

In addition to white office paper used every day, sometimes there is a need for non-standard types. It can be colored, photo or very thick paper. Due to the high cost and the lack of need to purchase large quantities, the packages in the box do not contain the same number as packs of A4 paper in the Svetokopi box. This is due to a different packaging of sheets; there is much less special type of paper.
One package contains 20, 50 or 100 sheets of photo paper. If this is not a professional photo studio, it’s unlikely that anyone needs a larger quantity, so they don’t buy it in boxes. The average density of a standard sheet is about 200 g/m2. Paper with a density higher than 300 g/m2 is used even less frequently, which is why it is sometimes sold one sheet at a time.
Colored paper comes in the same weight as regular white office paper. Therefore, you can purchase one package with a quantity of 500 sheets. This means that there will be the same quantity as there are packs of white A4 paper in a box. Due to the fact that the need for multi-colored paper is not so great, sheets of different shades are usually packaged in one package.
If in special cases you need very thick, designer or other non-standard paper, then it is usually sold in small volumes. Due to the high consumption of office paper in daily office life, it is more convenient to purchase it in boxes. How many packs of A4 paper are in a box will depend on the number of sheets in the pack and their density.
A4 is a representative of the A line of formats. These are standardized paper sizes used in most countries of the world, introduced in the 20s of the last century on the initiative of the German engineer and mathematician Walter Portsmann, one of the creators of the DIN standards system.
The aspect ratio of all sheets of this format ruler is the same – if the short side is taken as one, then the long side will be equal to the root of two (1: 1.4142). If a sheet with such proportions is folded in half along the long side, then the resulting “halves” will have the same aspect ratios.
The maximum sheet size for ruler A is one meter square (side length 841 x 1189 mm). It was named A0. When folded in half, A1 sheets are obtained, when folded again, A2 sheets are obtained, and so on.
Series A formats are not the only international standard that defines the dimensions and proportions of a paper sheet. There are also lines of formats B and C, but they are dealt with mainly by specialists in the field of printing. Their aspect ratio is the same, but the “reference points” are different – for sheets of B0 format the length of the short side is one meter (while for A0 it is only 841 mm).
Notice the “home” for your money.
If you want financial prosperity, then it’s time to pay attention to where your money “lives”. Some people keep their money in their trouser pockets, in their shirt pockets, others keep them crumpled up in a shopping bag, thereby showing their disdain for money. But most people keep money in their wallet – and rightly so.
Few people pay due attention to the wallet itself – they’ll buy whichever one is cheaper and rejoice: “What difference does it make where to keep the money, this one will do.” But it won’t do! The wallet should be expensive, because the amount of money depends on the “house” in which money lives: if they like it there, then they will multiply there, thereby increasing your well-being.
So don’t skimp on your wallet, it will be a kind of totem for you. Buy yourself a solid wallet made of expensive leather with a large number of compartments (including for small change). Allow yourself this luxury and do not spare money – it will come back to you a hundredfold. Maybe your prosperity will begin with this “hand safe”; as they say, the wallet will “attract” everything else.
5. Watch how you name money.
Money cannot be neglected, therefore it is not worth calling it derogatory. What do you call money – stolnik, ten, thousand, mower, babki? It is better to use affectionate names, such as “Katenka” – 100 rubles, “zelenenky” – dollar, “Jewish, evrik” – euro.
You also need to watch out for phrases that show that you don’t respect money. “Well, what can you buy today with a stolnik?”, “One hundred rubles is not money,” or “There’s nothing to do with a thousand in the store today.”
Did anyone recognize their favorite phrases? And after that you want to get rich? Yes, all these phrases are simply imbued with hatred of money! Stop talking urgently, because until you love and begin to respect money, it will definitely not come to you in large quantities and will not love you.
You may not believe in money magic, the magic of attracting and saving money, but is it difficult to just try? What if the old advice will help you too?
A banknote of five thousand rubles is currently the largest denomination banknote in the country. The images on it are dedicated to the city of Khabarovsk. On the front side, in the foreground, you can see a monument to Nikolai Muravyov-Amursky, a figure of the 19th century who did a lot for Eastern Siberia, and a drawing of the Khabarovsk embankment. The reverse shows the famous bridge across the Amur in this city.
Now you can find 2 types of banknotes with a face value of 5,000 rubles: a banknote developed in 1997 (in free circulation since 2006), and a later modification of 2022 (issued since 2022). Five thousand banknotes are considered to be the most “long-lived” – on average, one banknote is used for more than four years.
The more uniform the paper structure, the better the printing level. Areas of uneven distribution of fibers perceive ink worse, and text, and especially the image, in such places will be of poor quality.
In an office setting, I will check the opacity by holding the sheets of paper to a light source.

Features of the influence of the size of cardboard boxes on their weight
The dimensions of cargo directly affect the size of the cardboard boxes used to transport them – this is a well-known fact. But everyone somehow forgets about the fact that large-sized cargo often has quite a lot of weight. This is important for us in this case, since the type of cargo transported greatly affects the weight of cardboard boxes. Everything is simple here: if you transport heavy goods in thin boxes made of single-layer cardboard, and even in damp conditions, for example, then there can be no question of reliable packaging and keeping the goods safe and sound. Large-sized corrugated packaging must be designed to transport goods in any conditions, therefore, for its manufacture, exclusively durable and dense materials are used, which weigh a lot. Well, a complex design or configuration of a cardboard box for large-sized cargo generally requires the use of at least five-layer corrugated cardboard, capable of withstanding any external influences and expected static and dynamic loads.
Most often, multilayer corrugated cardboards of increased strength are used for the production of corrugated cardboard transport boxes intended for packaging large goods or cargo. For example, this is three-layer corrugated cardboard brand T-25 or five-layer corrugated cardboard brand P-30.
They optimally combine the characteristics of strength and protection and are relatively inexpensive. But the weight of such transport boxes will be quite large, in some cases even more than five kilograms! There are many forms of large containers made from these types of corrugated cardboard (containers, boxes, trays, etc.).
However, four-flap cardboard boxes are most often used for storing and transporting standard large-sized goods. These packaging products provide reliable protection of goods, objects and cargo that are placed in them from mechanical negative external influences, weather factors, temperature changes and increased humidity levels.
The average weight of a four-valve transport box made of three-layer corrugated cardboard depends on its volume. So, a package with a volume of 125 liters weighs approximately 900 grams, a reinforced box with a volume of about 70 liters weighs about 500 grams, and a four-valve box without top valves with a volume of 30-40 liters weighs about 450 grams.
The heaviest are four-flap boxes made of five-layer corrugated cardboard, as well as five-layer wardrobe boxes, which are used when moving. They are made from heavy-duty corrugated cardboard and can weigh up to two kilograms or even more.
And for the convenience of transporting objects and cargo in such heavy cardboard boxes, cut-out handles are provided, as well as special grooves in the corners of the bottom of the box and special notches on the lid, with the help of which such corrugated boxes are clearly fixed when installed on top of each other.

How many pixels in a4 format
It is impossible to say exactly how many pixels “fit” in the A4 format – after all, a pixel does not have its own “dimension”, and how clear and detailed the image is depends on the number of pixels per inch. Accordingly, the number of pixels in the image that can be used to completely “print” an A4 sheet without margins will depend on the resolution of the image. You can calculate it by knowing the dimensions of A4 in inches (11.75×8.25) and the dpi of the image (the number of pixels per inch).
So, with a resolution of 72 dpi, the sheet size will correspond to a picture that has 846 pixels on the long side and 594 on the short side. With a resolution of 300 dpi, which allows you to obtain a fairly clear and high-quality image when printing, you will need a photo of 3525 by 2475 pixels. In total, such an image should contain 8.7 megapixels.
There are several varieties of stationery paper format. The most common are A3 and A4. The weight of a pack of A4 paper is 2.5 kilograms. A product in A3 format is twice as heavy – the weight of the pack is 5 kg. The standard dimensions of an A4 paper sheet are 210×297 mm, and an A3 sheet is 297×420 mm.
The weight of a pack of A4 paper is 2.5 kg.
Things surrounding a person may vary in purpose, cost and frequency of their use. Paper has long and firmly belonged to the category of things “closer” to humans. Having learned to crawl, the baby reaches for pencils and a piece of paper to embody his creative abilities on a white sheet, his still inept fingers draw a yellow speck of the sun, like a dandelion, blue puddles and the kind eyes of his mother.
At a school desk, a grown-up child transfers his knowledge onto paper in notebooks or onto a landscape sheet. In adulthood, for a person, paper can become an official document, a book manuscript or a diary, storing his thoughts, experiences and joys.
Paper is one of the great inventions of mankind. The copyright is attributed to the Chinese Cai Lun, but there is no documentary evidence of this, especially since earlier historical artifacts dating back to the 2nd millennium BC were found in China.
Paper is used not only as a material for writing; Catherine the Great introduced paper banknotes into circulation, which were affectionately dubbed by the people after the Empress’s favorite “Katenka”. Before the paper ends up on the desk, it goes through a rather long and difficult processing process.
Economics of paper bag production
This in-depth formula is designed specifically to allow non-specialists to calculate the cost of paper bags. The formula was developed by Svetlana Ermolaeva, a senior specialist in paper and paper packaging. Tel.: 8-800-350-06-15, (4922) 26-08-49.
CALCULATION OF THE COST OF PAPER BAGS
In order to find the cost of paper per bag, you need to find the weight of one bag, based on the parameters of the bag itself and the paper.
P – paper density (g/m²). Mainly for paper production
bags, paper with a density of 70 g/m² is used.
F – paper size (cm).
L – bag length (cm)
B – bag width (cm)
B1 – width of the bottom of the bag (cm)
K – number of layers
L1 – workpiece length (cm):
for open bag: L1=B1×0.75 L
for a closed bag: L1=B1×1.5 L
PL – cover sheet weight (g):
for open bag:
PL=(B-B1) ×B1×P /10,000
for a closed bag, taking into account the weight of the paper valve
(valve weight is equal to the weight of one cover sheet):
PL=(B-B1) ×B1×P /10,000 ×3
We insert the above parameters into the formula
to calculate the weight of a paper bag:
Bag weight (g) = L1×F /100×P /100×K PL
Convert the weight of the bag into kilograms:
Bag weight (kg) = Bag weight (g) / 1,000
Find the number of bags from 1 ton of paper:
1,000 (kg) / bag weight (kg)
Cost of paper per bag (RUB):
Price of 1 ton of paper / number of bags of 1 ton of paper
The cost of glue per bag is on average 0.14 rubles.
Depends on the type, size and number of layers of the bag.
The cost of flexo paint per bag is on average 0.20 rubles.
Depending on the colors and degree of filling of the canvas.
Cost of work to produce a bag on equipment
of the Meshkodel company on average:
for open – 0.37 rub.
for closed – 0.68 rub.
Other expenses average RUB 0.08. for one bag.
If the bag is combined (consists of different types of paper), for example, the top layer is white kraft, the rest are regular kraft and a polyethylene liner, the cost of paper is calculated separately, as for three bags. In this case, the weight of the internal layers and the polyethylene liner is calculated without the weight of the cover sheet (PL).
On average, the profitability of products (manufactured bags) is 30-40%. The payback period for equipment is 1-1.5 years.
