The use of paper sheets in different formats for people living in the 21st century is how to wake up every day and brush your teeth. Few people know that at the beginning of the 20th century there were no standards on what a sheet of paper should be for writing reports, reviews or just maintaining a home 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 themselves. Creative people at that time preferred to work with paper, which was called the "Golden Section".
The ratio of the sheets of this line was 1: 1,168. However, for other industries, it was not quite suitable. The first to propose the introduction of a single standard for the format of paper sheets was German Walter Portsmann. He gave birth to sheets whose aspect ratio was 1: 1.414, and the total area of the sheet was one square meter.
A4 sheet sizes
Not everyone who uses such paper knows how much a sheet of A4 paper weighs and what size it is. Sheets of this format have exactly the same size. It is one sixteenth of a square meter. The diagonal of sheet A4 is 364 mm.
This sheet was obtained by folding A0 paper in half. By the way, today A0 is almost forgotten. Occasionally, it is used for wall newspapers in schools or kindergartens.
So how much does A4 sheet weigh?
It would seem that getting an answer to this question is very simple - put a sheet on the scales and you know the answer. However, not all scales are able to show weight accurate to 0.01 g. Many who consider themselves to be a savvy person put a package of paper on the scales and weigh it, then divide by the number of sheets and think that they will get the correct answer.
However, you need to consider the weight of the package itself. Therefore, in this case, you need to take sheets without a wrapper, and the answer will be more accurate.
When weighing on more accurate scales in order to find out how much A4 sheet weighs, it was revealed that its weight is 4.9 g. Accordingly, the packaging of such sheets in the amount of 1000 sheets will weigh 4.9 kg. Some sources claim that the weight of the A4 sheet is 5 g. It is important to take into account the fact that A4 sheets can have different densities. Weight 4.9 g has a standard A4 with a density of 80 g per square meter.
The history of this invention of mankind has not been thoroughly studied. Since 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.
