Mesh to Micron Converter
Use our mesh to micron converter to convert mesh to micron instantly using US mesh to micron reference values. Includes a mesh size to micron chart, mesh to micron conversion table, and answers like how many microns is 100 mesh.
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.
A common approximation used for many US mesh ranges (often ~50–400 mesh). Use a table for the most accurate reference.
This matches the common reference value for how many microns is 100 mesh.

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
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.
A common US mesh to micron reference is about 149 microns for 100 mesh.
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.
It’s a side-by-side view (mesh to micron conversion table) showing what micron opening size corresponds to each mesh size.
Yes—use the same table in reverse: find the closest micron value and read the corresponding mesh size.
Yes—this page uses common US mesh to micron reference values used for standard sieve comparisons.
