Mesh To Micron Converter
Convert US sieve mesh numbers to microns and microns to mesh with standard Tyler mesh equivalents for filtration and particle sizing.
Mesh Size and Micron Particle Size
Mesh size describes how many openings exist per linear inch in a sieve screen. Microns (μm) measure the actual particle diameter. In filtration, grinding, and powder processing, engineers convert between mesh numbers and micron sizes to specify particle limits and screen requirements.
How Mesh Relates to Microns
Higher mesh numbers mean finer screens with smaller openings. For example, 100 mesh corresponds to particles passing through openings of about 149 microns, while 400 mesh corresponds to about 37 microns.
Common Mesh to Micron Values
- 40 mesh ≈ 420 μm
- 80 mesh ≈ 177 μm
- 100 mesh ≈ 149 μm
- 200 mesh ≈ 74 μm
- 325 mesh ≈ 44 μm

Frequently Asked Questions
What does 100 mesh mean?
100 mesh means a sieve has 100 openings per linear inch. Particles that pass through a 100 mesh screen are generally smaller than about 149 microns.
How many microns is 200 mesh?
200 mesh is approximately 74 microns using standard US Tyler sieve equivalents.
Is a higher mesh number finer or coarser?
Higher mesh numbers are finer. A 400 mesh screen has smaller openings than a 40 mesh screen.
What is the difference between mesh and microns?
Mesh is a screen count per inch, while microns measure actual particle or opening size in micrometers. Microns give a direct physical dimension.
Does this use US or UK mesh standards?
This converter uses standard US Tyler sieve mesh equivalents commonly referenced in filtration and powder sizing tables.
