An instrument called micrometer is used to measure paper or card thickness.
Paper measurement If we're talking about weight, the worldwide standard is gsm (grams per square meter), and there are no practical differences in the measuring technique; nevertheless, we may measure paper thickness by GSM. A4 paper measures 210 mm by 297 mm.
The typical thickness of easel paper is 0.1 mm. Teachers typically use easels and easel paper when teaching a math or english lesson rather than using the chalkboard.
Depends on what paper you're talking about. The average sheet of 20lb copier paper is 0.0038 inches thick; whereas the average sheet of cardstock is 0.0175 inches thick. For a great resource of various thicknesses visit http://iconix.biz/info/paper-weights.htm
the yield strength of Q345B is 345MPa for thicknesses <= 16 mm. 325MPa for 16 mm < thickness <= 35 mm. 295MPa for 35 mm < thickness <= 50 mm. 275MPa for 50 mm < thickness <= 100 mm.

A millimeter is the smaller unit of distance used for measuring small lengths .The thickness of nails and paper in a book is also measured in mm. also ,1 mm=0.1 cm =0.01 mm.
0.0508 mm
1.024 mm
0.405 mm
Paper comes in many different sizes, so there is no set conversion. However, GSM stands for grams / square meter, so if the GSM and density of the paper is known, conversion becomes easier. The formula for the thickness then becomes: Thickness = GSM/density.
