What is Mesh to Micron Conversion?

Mesh to micron conversion translates a mesh number (how many openings per inch) into an approximate opening size in microns (µm). This is commonly used for sieves, filtration, powders, and particle sizing.

US mesh to micron values are based on standardized sieve openings, but mesh to micron is not perfectly exact in every real-world screen because wire thickness and manufacturing tolerances can change the actual opening size.

If you’re searching convert mesh to micron or mesh to micron size, the fastest way is to use a mesh size to micron chart (mesh to micron conversion table). For example, how many microns is 100 mesh? It’s commonly listed at about 149 microns for US standard sieve references.

Mesh to Micron Conversion (How It Works)

Mesh is the number of openings per inch, while microns measure the opening size. Because wire thickness affects the opening, most mesh to micron conversions use standard reference tables (US Standard Sieve) and/or approximations.

Rule of thumb (approximation)
Microns ≈ 14900 ÷ mesh

A common approximation used for many US mesh ranges (often ~50–400 mesh). Use a table for the most accurate reference.

Example: convert mesh to micron
100 mesh ≈ 14900 ÷ 100 = 149 µm

This matches the common reference value for how many microns is 100 mesh.

Mesh
= Number of openings per linear inch of screen (US mesh).
µm
= Micron (micrometer) = one-millionth of a meter; used for opening/particle size.
Note
= Mesh to micron comparison is typically approximate unless you’re using a specific standard/table for a given sieve series.

How to Convert Mesh to Micron

  1. 1

    Enter the mesh size (US mesh) you want to convert.

  2. 2

    Use the mesh to micron converter to get the approximate micron opening size.

  3. 3

    For quick reference, use the mesh size to micron chart (mesh to micron conversion table) below.

  4. 4

    If you need a reverse lookup (micron to mesh size chart), find the nearest micron value in the table and read the mesh size.

Frequently Asked Questions

How to convert mesh to micron?

Use a mesh to micron converter or a mesh to micron conversion table (mesh size to micron chart). For a quick estimate, microns ≈ 14900 ÷ mesh.

How many microns is 100 mesh?

A common US mesh to micron reference is about 149 microns for 100 mesh.

Why is mesh to micron conversion approximate?

Mesh counts openings per inch, but the wire thickness changes the opening size. Different materials and weaves can slightly change the micron opening for the same mesh.

What is a mesh to micron comparison?

It’s a side-by-side view (mesh to micron conversion table) showing what micron opening size corresponds to each mesh size.

Do you have a micron to mesh size chart?

Yes—use the same table in reverse: find the closest micron value and read the corresponding mesh size.

Is this US mesh to micron?

Yes—this page uses common US mesh to micron reference values used for standard sieve comparisons.
