MESH and MICRON SIZES ISM
Mesh size or mesh number indicates both the number of filaments or wires per linear inch of fabric or wire filter cloth and the filament or wire diameter. As mesh number increases, the size of openings decreases. Mesh size is not a precise measurement of particle size because of the size of the wire used in the screen.

Mesh Size and Micron Conversion Chart — Skylighter, Inc.
The number of openings is the mesh size. So a 4 mesh screen means there are four little squares across one linear inch of screen. A 100 mesh screen has 100 openings, and so on. Note, therefore that as the number describing the mesh size increases, the particle size decreases. Higher numbers = finer powder.
