Mesh Size to Micron and MM: Fast Reference
These are common reference values buyers search for first. Final aperture still depends on wire diameter and weave type.
100 mesh to micron
100 mesh is commonly about 149 micron, or about 0.149 mm. It is often used for hydraulic oil, water treatment and general filtration.
200 mesh to micron
200 mesh is commonly about 74 micron, or about 0.074 mm. It is often used for filter discs, polymer filtration and fine liquid filtration.
400 mesh to micron
400 mesh is commonly about 37 micron, or about 0.037 mm. For high precision filtration, confirm wire diameter and open area before ordering.
Need to buy mesh by micron rating?

Common Mesh to Micron Conversion Table
The values below answer common searches such as mesh to micron, mesh to mm, micron table and mesh size in mm. They are useful for early selection, but the final stainless steel woven mesh aperture must be confirmed by wire diameter, weave type and inspection tolerance.

Buying Stainless Steel Filter Mesh by Micron Rating
Many buyers reach this chart from searches such as mesh to micron, micron table, 100 mesh to micron or 200 mesh to mm. For purchasing, the next step is to convert the reference value into a real factory specification.
For mesh rolls
Send material grade, mesh count, wire diameter, roll width, length, quantity and packing requirement.
For filter discs
Send disc diameter, layer structure, mesh specification, edge treatment, tolerance and quantity.
For OEM filter parts
Send drawings, samples, application conditions, target micron, repeat order plan and delivery country.

How B2B Buyers Should Specify Filter Mesh
1. Start With Filtration Target
Use micron rating to describe particle retention. If you only know mesh count, use the chart as a quick estimate.
2. Confirm Material Grade
Choose 304 for general use, 316/316L for chemical, food, pharmaceutical, marine or chloride exposure.
3. Send Complete RFQ Data
Include mesh count, micron target, wire diameter if known, size, quantity, application and delivery country.
Citation-Friendly Summary
Mesh count is openings per linear inch. Micron rating describes opening size. For woven stainless steel mesh, aperture can be calculated when wire diameter is known: opening in mm = 25.4 / mesh count - wire diameter in mm. Without wire diameter, mesh-to-micron charts are only common reference values.
How to Cite This Resource
Need the Correct Mesh for a Real Filter?
Do not choose only by chart value. If the filter controls production quality, send the target particle size, liquid or powder type, temperature, pressure, cleaning method and quantity. ANPING MAOYE can help compare 304 and 316L stainless steel mesh options for quotation.

Mesh Count and Micron FAQ
Is mesh count exactly the same as micron rating?
No. Mesh count is openings per linear inch. Micron rating describes the approximate opening size. Wire diameter and weave type affect the real aperture, so the same mesh count can have different micron openings.
Can I use this chart for a purchase order?
Use it as a starting reference only. For purchase orders, confirm material grade, wire diameter, measured aperture, aperture tolerance, roll width or part dimensions, quantity and application.
What mesh is common for liquid filtration?
100 to 300 mesh is common for many liquid filtration projects, but the correct choice depends on fluid viscosity, pressure, particle size and cleaning method.
Can ANPING MAOYE make custom mesh discs or filter parts?
Yes. We can discuss rolls, sheets, discs, cylinders, baskets and OEM mesh parts based on drawing, sample or clear dimensions.
How many microns is 100 mesh?
100 mesh is commonly referenced as about 149 micron, or 0.149 mm. For a purchase order, confirm the wire diameter and measured aperture with the supplier.
How many microns is 200 mesh?
200 mesh is commonly referenced as about 74 micron, or 0.074 mm. It is a common fine filtration choice, but open area and wire diameter still affect flow rate.
How do I convert mesh to mm?
Use the aperture in micron and divide by 1000. For example, 149 micron is 0.149 mm and 74 micron is 0.074 mm. If wire diameter is known, aperture in mm can be estimated as 25.4 divided by mesh count minus wire diameter in mm.
Need a Mesh Recommendation?
Send your application, micron target, size and quantity. We can suggest 304/316L mesh options and factory-direct quotation details.
40 Mesh to MM: Quick Reference
40 mesh is about 0.635 mm pitch because one inch is 25.4 mm and 25.4 / 40 = 0.635 mm. The actual open aperture is smaller than 0.635 mm after subtracting wire diameter.
| Search question | Quick answer | Buyer note |
|---|---|---|
| 40 mesh to mm | Approx. 0.635 mm center-to-center pitch | Opening size depends on wire diameter. |
| 40 mesh to micron | 635 microns pitch before wire diameter deduction | Do not treat mesh count as exact filtration micron rating. |
| For stainless steel filter mesh | Send mesh count plus wire diameter | This helps ANPING MAOYE quote the real aperture and material cost. |
For industrial filtration projects, buyers should specify material grade, mesh count, wire diameter, roll width, quantity and application instead of using mesh count alone.
