Does higher mesh mean smaller particles?
Generally yes. Higher mesh counts correspond to smaller sieve openings.

About this converter
How to use Mesh to Micron Converter, plus the formulas and logic behind the results.
Tool description
Mesh count and opening size depend on wire diameter and sieve standard. This educational estimate uses opening in microns ≈ 15,000 ÷ mesh.
How to use
- Enter the mesh count or opening value.
- Choose the direction matching the unit you entered.
- Select Calculate to apply the conversion factor.
- Review the result in mesh or microns.
Formulas & reference
opening (µm) ≈ 15,000 ÷ meshmesh ≈ 15,000 ÷ opening (µm)
Calculation logic
The tool uses a reciprocal approximation. A larger mesh count therefore produces a smaller estimated opening.
Approximation only: actual apertures vary by standard and wire diameter. Use a certified sieve chart for engineering or quality-control work.
Mesh to Micron Converter FAQ
Common questions about this conversion and how to interpret the result.
Is mesh-to-micron conversion exact?
No. Wire thickness and the sieve standard affect the actual opening.
What formula does this tool use?
It uses the educational estimate microns ≈ 15,000 divided by mesh.
What is 100 mesh in microns?
The formula estimates about 150 microns; a specific standard sieve may differ.
Can I specify a sieve standard?
No. Consult ASTM E11, ISO 3310, or manufacturer data for certified values.
Why must the input be positive?
The reciprocal formula is undefined at zero and mesh size cannot be negative.
