Engineering Tool
Mesh / Micron / Wire Gauge Converter
aperture(µm) = 25,400 / mesh − wire Ø(µm). Works both directions, with SWG gauge lookup and open-area check for square-weave cloth.

This tool provides preliminary estimates only, based on generalized correlations and typical service assumptions. Actual performance depends on operating conditions, fouling, turndown, mist load, and vessel internals. Results must be verified by a qualified process engineer before purchase or fabrication. Meshium accepts no liability for decisions made solely on this output.

Why mesh count alone never defines a cloth
"100 mesh" only says there are 100 openings per inch — it says nothing about the size of those openings until you fix the wire diameter. The same 100 mesh woven with Ø0.10 mm wire gives a 154 µm aperture and ~37% open area; with Ø0.14 mm wire it drops to a 114 µm aperture and ~20% open area. Filtration cut point, flow resistance and cloth strength all move with that choice.
That is why our quotations always lock mesh count, wire diameter, weave type and material together — and why every shipment includes measured (not nominal) aperture and wire values in the QA report.
