To convert grammage (gsm) of paper into thickness (mm), you must know the density of the paper. Paper density varies depending on the type of paper. However, as a general approximation, you can convert by using the formula: thickness (mm) = gsm / density (g/cm³).

It really depends how big the piece of paper is, but a good idea would be square centimetres.ExamplesA0 paper is such that it has an area of 1m2 or 10000cm2.A4 paper has an area of 1/16m2 or 625cm2.
For 80 gsm paper, it is approx 2.495 kilograms.
There are 62,370 1 millimeter squares in a sheet of A4 graph paper that measures 210 mm by 297 mm. This calculation is obtained by multiplying the length of the paper (210 mm) by the width of the paper (297 mm).
To convert 0.9 dm to mm, you would multiply by 100 because there are 10 mm in 1 dm. Therefore, 0.9 dm is equal to 90 mm.
To convert centimeters (cm) to millimeters (mm), you multiply the number of centimeters by 10. This is because there are 10 millimeters in 1 centimeter. For example, to convert 5 cm to mm, you would multiply 5 by 10 to get 50 mm.
