Mesh Size and Micron Conversion Chart — Skylighter, Inc.
So, beyond 325400 mesh, we usually describe particle size in "microns." What is a micron? A micron is another measurement we use for measuring particle size. A micron is onemillionth of a meter or one twentyfive thouh of an inch. This table is adapted from a post made by Ken Kosanke to the PML and previously published in a PGII Bulletin.
