Using paper sheets in different formats for people living in the 21st century is like waking up every day and brushing your teeth. Few people know that at the beginning of the 20th century there were no standards for what a piece of paper should be for writing reports, reviews, or just keeping a notebook.
A4 sheet history
In the twentieth century, the format of the sheets that were used for work was chosen by each company, factory or any other production for itself. Creative people at that time preferred to work with paper, which had the name "Golden Section".
The sheet ratio of this line was 1:1, 168. However, it was not quite suitable for other industries. The first to propose a single standard for the format of sheets of paper was the German W alter Portsmann. He gave life to sheets whose aspect ratio was 1:1, 414, and the total area of \u200b\u200bthe sheet was one square meter.
A4 sheet sizes
How much a sheet of A4 paper weighs and what size it is, not everyone who uses such paper knows. Sheets of this format have exactly the same size. It is one sixteenth of a square meter. The diagonal of A4 sheet is 364 mm.
This sheet was obtained by folding A0 paper in half. By the way, these days A0 is almost forgotten. Occasionally it is used for wall newspapers in schools or kindergartens.
So how much does an A4 sheet weigh?
It would seem that getting an answer to this question is very simple - put the sheet on the scales and you know the answer. However, not all scales are capable of displaying weights to the nearest 0.01g. Many who consider themselves to be savvy put a package of paper on the scale and weigh it, then divide by the number of sheets and think they will get the correct answer.
However, you need to take into account the weight of the package itself. Therefore, in this case, you need to take sheets without wrapping, and the answer will be more accurate.
When weighed on more accurate scales in order to find out how much an A4 sheet weighs, it was found that its weight is 4.9 g. Accordingly, a package of such sheets in the amount of 1000 sheets will weigh 4.9 kg. Some sources claim that the weight of an A4 sheet is 5 g. It is important to take into account the fact that A4 sheets can have different densities. Weight 4.9g has a standard A4 with a density of 80g per square meter.
The history of this invention of mankind has not been thoroughly studied. Because in today's world, few people delve into such details and moments. Most of us take everything for granted, and sometimes even neglect certain human achievements, while other people living in poor countries are not even aware of some of the benefits of civilization.
