    For example, a 36 mesh screen will have 36 openings while a 150 mesh screen will have 150 openings. Since the size of screen (one square inch) is constant, the higher the mesh number the smaller the screen opening and the smaller the particle that will pass through. Generally US Mesh is measured using screens down to a 325 mesh (325 openings in(PDF) SIGNIFICANT ROLE OF SOXHLET EXTRACTION ,The screen size indicates the number of openings in the mesh screen per inch.
