What is the formula to convert mesh to microns?

The standard formula is: Microns = 25,400 ÷ Mesh Size. For example, 400 mesh = 25,400 ÷ 400 = 63.5 microns (theoretical). In practice, actual particle sizes are slightly smaller due to wire thickness and sieving efficiency, so we also show practical values in the converter.

What is 600 mesh to micron?

The theoretical size for 600 mesh is 25,400 ÷ 600 ≈ 42.3 microns. In practical industrial use, 600 mesh is typically treated as about 20 microns because particles must be smaller than the sieve opening to pass consistently.

What is 1000 mesh to micron?

The theoretical size for 1000 mesh is 25,400 ÷ 1000 = 25.4 microns. Practical particle sizes for 1000 mesh fillers are usually around 10 microns for calcite and GCC.

How do I convert microns to mesh size?

To convert microns to mesh, use the inverse formula: Mesh Size = 25,400 ÷ Microns. For example, 38 microns corresponds theoretically to about 668 mesh, but in practice is associated with 400 mesh for mineral fillers. Our converter uses a practical lookup table to return realistic mesh values.

What is Mesh Size?

Mesh size refers to the number of openings per linear inch in a sieve. Higher mesh numbers indicate finer particles.

What are Microns?

A micron (μm) is one-millionth of a meter. It's the standard unit for measuring particle sizes in industrial applications.

Conversion Formula

Microns = 25,400 ÷ Mesh Size
Mesh Size = 25,400 ÷ Microns
