80 Mesh to Micron – Opening Size in µm & mm
80 mesh ≈ 177 µm
A US standard 80 mesh sieve has openings of about 177 µm (0.177 mm, 0.007 in).
Step by step
- Mesh 80 means about 80 openings per linear inch.
- Opening size depends on wire thickness, so it is read from the standard sieve series (ASTM E11).
- 80 mesh ≈ 177 µm.
80 mesh separates medium to fine sand, flour-sized particles and many powders.

How it works
Mesh number counts the openings per linear inch of a woven screen. Because the wire takes up space, the opening is smaller than 25.4 mm divided by the mesh count, and different wire gauges give different openings — so standard sieve series fix the exact opening for each number. Values here follow the US standard series; Tyler mesh numbers are close but not identical.

Frequently asked questions
What is 80 mesh in microns?
About 177 µm.
What is 80 mesh in mm?
0.177 mm.
Is higher mesh finer?
Yes — more openings per inch means smaller openings.
What is the difference between US and Tyler mesh?
They are two standard series with nearly the same openings; the numbers differ slightly for some sizes.
