Use this mesh to micron converter to compute between two different systems of measuring: the mesh scale and the micron scale.
- Mesh refers to the number of openings per linear inch in a sieve or screen.
- Micron (μm) is a unit of length equal to one-millionth of a meter.

Mesh to Micron Conversion Formula
Microns ≈ 25400 / (Mesh Size)This formula provides a rough estimate and works best for mesh sizes between 5 and 270.
Let’s convert a 100 mesh screen to microns:
Apply the formula: 25400 / 100 = 254 microns
The actual standardized value is closer to 149 microns.
