How to Convert Mesh to Micron?

To convert Mesh to Microns, divide 25400 (microns per inch) by mesh number. For example, a 400 mesh screen equals 25400/400 = 63.5 microns. Different mesh standards may have slightly different conversion factors, so always specify which standard you’re using. The relationship is inversely proportional: higher mesh numbers mean smaller openings.

Mesh to Micron Conversion Formula

Basic Mesh to Micron Formula:

Microns = 25400 ÷ Mesh Number
where:
25400 = Number of microns in one inch
Mesh Number = Number of openings per linear inch

Micron to Mesh Formula:

Mesh Number = 25400 ÷ Microns
where:
Microns = Opening size in micrometers
25400 = Microns per inch

Alternative Units:

Millimeters = Microns ÷ 1000
Inches = Microns ÷ 25400

Example 1: Standard Fine Mesh

  • Mesh Size = 325
  • Microns = 44
  • Millimeters = 0.044
  • Standard = US Mesh
  • Application = Fine Powder Analysis

Example 2: Coarse Screen

  • Mesh Size = 60
  • Microns = 250
  • Millimeters = 0.250
  • Standard = Tyler
  • Application = Sand Screening

Example 3: Ultra Fine Mesh

  • Mesh Size = 400
  • Microns = 37
  • Millimeters = 0.037
  • Standard = US Mesh
  • Application = Particle Size Analysis

Example 4: Medium Screen

  • Mesh Size = 100
  • Microns = 149
  • Millimeters = 0.149
  • Standard = British
  • Application = Material Classification

Example 5: Industrial Screen

  • Mesh Size = 200
  • Microns = 74
  • Millimeters = 0.074
  • Standard = US Mesh
  • Application = Industrial Filtering

What is Mesh and Micron?

Mesh refers to the number of openings in one linear inch of screen or sieve material. A higher mesh number indicates finer screen openings.

Micron (micrometer) is a metric unit equal to one-millionth of a meter or one-thousandth of a millimeter. Mesh is commonly used in industrial applications while Microns are preferred in scientific and technical contexts.
