Particle Size Conversion Table | Sigma-Aldrich
Large sieve openings (1 in. to 1/4 in.) have been designated by a sieve "mesh" size that corresponds to the size of the opening in inches. Small sieve "mesh" sizes of 3 1/2 to 400 are designated by the number of openings per linear inch in the sieve. The following convention is used to characterize particle size by mesh designation:

Mesh (scale) - Wikipedia
Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material.For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.

This count is the mesh number. A 4 mesh screen means there are four little square openings across one inch of screen. A 100 mesh screen has 100 openings per inch, and so on. Note: As the number indicating the mesh size increases, the size of the openings and thus the size of particles captured decreases. Higher mesh numbers = finer particle sizes.
