Particle Size Conversion Chart | Williams Patent Crusher

Mesh vs. Microns. Mesh size refers to the number of openings in one inch of screen. For example, a 4-mesh screen means that there are four squares within one inch of the screen. As the mesh size increases, the particle size decreases to create a finer material. Mesh size is not a precise measurement of particle size, but it is a fair estimation.
