Mesh to Micron Converter (Tyler & US Standard

Mesh number indicates the number of openings per linear inch in a sieve screen. Higher mesh numbers = smaller particle openings. Used in pharmaceuticals, food processing, mining, and filtration.

To use the Mesh to Micron Converter (Tyler & US Standard), enter your Mesh Number, Mesh Standard. The calculator instantly computes Opening Size in Microns (µm), Opening Size in Millimeters and more. Results update in real time as you change any input — no submit button needed.

How to Use This Calculator

Enter your Mesh Number (e.g. 100 in mesh) and Mesh Standard — choose from US Standard (ASTM E11), Tyler Mesh Series. Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Microns ≈ 15,000 ÷ Mesh Number (US Standard)

Tyler ≈ 14,900 ÷ Mesh Number

1 mm = 1,000 µm | 1 inch = 25,400 µm

Worked Example

100 mesh US Standard: 15,000 ÷ 100 = 150 µm = 0.150 mm = 0.0059 in. Classification: Fine Sand (75-425 µm).

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
