Understanding Mesh and Micron Conversion
What is Mesh Size?
Mesh size refers to the number of openings per linear inch in a sieve or screen. It's a standard unit used to classify particle sizes in various industries. The higher the mesh number, the smaller the openings and the finer the particles that can pass through.
Relationship to Microns
Microns (micrometers) measure the actual opening size. There's an inverse relationship: as mesh number increases, the micron size decreases. This relationship isn't perfectly linear due to wire thickness variations in different mesh ranges.
Conversion Methodology
Standard Table Method
Uses ASTM E11 and ISO 3310-1 standard tables for precise conversions. This method provides the most accurate results for standard mesh sizes.
Approximation Formula
For mesh sizes 50-400: microns ≈ 14,900 / mesh
This provides a reasonable approximation but may not be as precise as standard tables.
