How to Use the Calculator

Converting between mesh sizes and microns is simple:

  • Select your conversion direction (Mesh to Microns or vice versa)
  • Enter your value in the input field
  • Click "Convert" to see results
  • View equivalent measurements in microns, millimeters, inches, and both ASTM and Tyler mesh sizes

Note: The calculator uses standard ASTM E11-20 mesh sizes and provides Tyler equivalents where available.

Understanding Mesh Sizes

Mesh size refers to the number of openings in a sieve per linear inch:

  • Higher mesh numbers indicate finer screens (smaller openings)
  • Lower mesh numbers indicate coarser screens (larger openings)
  • Common mesh sizes range from 3.5 (5600 microns) to 635 (20 microns)
  • Microns (μm) are direct measurements of particle size (1 micron = 0.001 mm)
ASTM vs Tyler Mesh

ASTM E11-20 Standard

  • Current international standard for test sieves
  • More comprehensive range of sizes
  • Used in most modern applications

Tyler Standard

  • Traditional standard still used in some industries
  • Based on a √2 progression between sizes
  • Compatible with ASTM sizes through conversion
Applications
  • Particle size analysis in material science
  • Quality control in manufacturing
  • Mining and mineral processing
  • Pharmaceutical particle sizing
  • Food and beverage processing
  • Chemical industry specifications
  • Research and development
  • Environmental testing
Frequently Asked Questions

Why are there different mesh standards?

ASTM and Tyler standards developed independently in different industries. While ASTM is now the international standard, Tyler mesh remains common in mining and mineral processing.

How accurate are mesh-micron conversions?

Conversions use standardized values from ASTM E11-20. The calculator finds the closest standard mesh size when converting from microns, as not all micron values correspond exactly to standard mesh sizes.

Which measurement should I use?

Use microns for precise particle size specifications. Use mesh sizes when working with physical sieves or when following industry standards that specify mesh numbers.
