Calculate paper weight and area. A calculator for the weight of sheets of paper in DIN formats from the grams per square meter inscription. Standard paper has a weight of 80 g/m², many other paper strengths and therefore weights occur. This weight can be taken from the package inscription. Enter the paper weight per square meter, the format and the number of sheets and click Calculate. The results are rounded to three decimal digits.
Example: 1,000 sheets of paper in DIN A4 format with the specified 80 grams per square meter weigh just under 5 kilograms, or more precisely, 4989.6 grams. They could cover 62.37 square meters of floor space if placed side by side without gaps and without overlapping. If you want to know how high these sheets are stacked, you can use the stack thickness calculator. In this case, it would be about 10 centimeters, but that, of course, depends on another quantity, namely the thickness of the sheets.
The numerical value after DIN X doubles the weight and surface area of a sheet of paper when it decreases by one. A DIN A3 sheet is therefore twice as large and heavy as a DIN A4 sheet, although the size refers to the surface area, not the length and width. These two values each increase with the square root of 2. For more information, see Paper Size; for the mathematical background, see Surface Area.
Weight is the colloquial term for what is officially called mass. Expressing a weight in kilograms is very common outside of physics. However, grams and kilograms denote mass, and weight is a force measured in newtons. The conversion factor between these two quantities is determined by the Earth's gravitational pull. And since we generally live on Earth, we can get by quite well with weight measurements in grams and kilograms, as long as we stay outside the circles of physicists and natural scientists. However, the physically correct term for this calculator would be paper mass and total mass.
