  • 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.
