Mesh to micron chart & table
Every row mirrors our calculator dataset — ideal for documenting QA stacks or quoting woven filters.
Numbers summarize handbook openings — see ASTM E11 vs ISO notes before contractual quoting.
Download CSV
Download the mesh-to-micron chart as CSV for spreadsheets, lab notebooks, purchasing packets, or engineering references — each row mirrors the live dataset.
Print-friendly: press Ctrl/Cmd+P — your browser can save PDF for lab notebooks.

Chart FAQ
- Is mesh the same as microns?
- No. Mesh counts wires per inch; microns describe particle size or opening — relate them using standardized sieve charts.
- Why do vendors disagree slightly?
- Wire diameter tolerances and wear change openings. Treat conversions as approximate references.
- Can I host this offline?
- Download the CSV and reuse internally — attribution appreciated.
- Does this CSV replace certified sieve paperwork?
- Never — CSV summarizes handbook openings for convenience only.
- Which column should procurement quote?
- Quote mesh count plus supplier micron tolerance bands tied to PO revisions.
- Where can I learn about ASTM vs ISO wording?
- See our sieve standards primer linked below.
