Mesh to Microns Sieve Converter (ASTM E11 Standard) | Nutradays
Instantly convert particle mesh size to microns, millimeters, and inches. Reference standard ASTM E11 sieve wire dimensions for bulk botanical extracts & active powders.
🔬 Mesh Aperture Visualizer (1" x 1")
Simulating relative aperture size. Higher mesh counts reduce the spacing between wire mesh threads, restricting passage to smaller particle sizes.
💡 Key Sourcing Benchmarks
- 80 Mesh: Standard for encapsulation. Offers optimal flow properties for capsule filling machines.
- 120+ Mesh: Ideal for beverage blends. Dissolves rapidly in liquids but can clump during handling.
- Note: Real-world screen wire thickness reduces actual aperture size. Refer to batch COAs for exact sieve parameters.

Procurement use
Use the result as a sourcing checkpoint, not a final specification.
Particle size affects flowability, dispersion, capsule filling, tablet compression and sensory feel. Use this conversion as an early check before confirming a botanical powder specification.
Confirm whether the supplier uses US mesh, ASTM sieve or internal particle size targets.
Ask if the quoted mesh is typical value, minimum passing rate or full particle distribution.
Check whether finer mesh changes price, lead time, flowability or moisture sensitivity.
Request batch COA or sieve analysis when particle size is critical to your formula.
Mesh conversion is a reference. Final purchasing decisions should rely on agreed specifications and current-batch test data.
