An instrument called micrometer is used to measure paper or card thickness.
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).
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.
120 lb paper is typically around 0.003 inches (0.076 mm) thick. The weight of paper is a measurement of its density, not its thickness, so the thickness can vary depending on the type of paper and its composition.
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 weight of paper is typically measured in grams per square meter (gsm), not by thickness. However, a general guideline is that a 2.4 mm thick paper may be around 220-230 gsm, but this can vary depending on the specific type of paper and its density.
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 common example of an item visible to the human eye with a thickness of 0.1 mm is a sheet of standard printer paper. Another example could be the thinnest human hair strands, which can also range around 0.1 mm in thickness.

The thickness of a penny is approximately 1.52 mm.
