Sieve mesh to millimeters

Type a value in mesh to get it in mm instantly.

15.24mm

That's 3.8× as coarse as gravel, while a pebble is 1.97× coarser. That is gravel: pebbles and cobbles.

What it means

What is that material?

Class boundaries follow the Wentworth scale. Mesh numbers are approximate: sieve standards differ between countries.

The math

How to convert mesh to mm

Mesh counts the openings per inch of sieve, allowing for the thickness of the wire: mm ≈ 15.2 ÷ mesh. A higher mesh number passes finer material.

Example: 1 mesh = 15.24 mm.
