Notes: Lookup values are from the commonly used US Standard Sieve Series (approx.). If a wire diameter is provided, the aperture is estimated as: aperture (µm) ≈ 25,400 ÷ mesh − wire_diameter. Real sieves follow ASTM E11 tables; wire diameters vary by mesh and manufacturer.
Microns → Mesh

This returns the nearest standard mesh from the internal table and also gives a quick‑estimate mesh using mesh ≈ 25,400 ÷ (µm + wire_diameter) if a wire diameter is provided.

Values are widely used industry approximations for ASTM/US Standard Sieve openings (informational; verify against your QA standard when critical).
