Mesh to Micron Converter
Convert mesh to microns instantly with our free online converter. Uses ASTM E11 standard lookup table with interpolation for accurate particle size conversion across 28 sieve sizes from 4 mesh to 400 mesh.
About This Calculator
Our Mesh to Micron Converter instantly converts sieve mesh numbers to micron particle sizes using the standard ASTM E11 lookup table. Whether you work in pharmaceuticals, mining, food processing, or construction, accurate particle size conversion is essential for quality control and material specification.
This converter includes all 28 standard mesh sizes from 4 mesh (4750 microns) to 400 mesh (38 microns) and performs linear interpolation for non-standard mesh numbers. Simply enter a mesh number and the tool displays the corresponding micron value, indicating whether it is an exact match or an interpolated estimate.
How It Works
The converter uses a curated lookup table based on ASTM E11 standard sieve specifications. Each standard mesh size has a precisely defined opening size in microns. For mesh numbers between standard sizes, the tool performs linear interpolation between the nearest adjacent standard values to provide an accurate estimate.
Common Applications
- Pharmaceuticals: Powder particle sizing for drug formulation and quality control
- Mining & Minerals: Ore grading and aggregate size classification
- Food Processing: Flour grinding, spice pulverizing, and ingredient sieving
- Construction: Aggregate and sand size specification for concrete and asphalt
- Water Filtration: Filter mesh selection based on required particle retention
Frequently Asked Questions
What is mesh size?
Mesh size refers to the number of openings per linear inch in a sieve screen. A higher mesh number means more openings per inch, resulting in smaller particle sizes. For example, a 100 mesh screen has 100 openings per inch and allows particles of approximately 150 microns to pass through.
How is mesh converted to microns?
Mesh to micron conversion uses a standardized lookup table based on ASTM E11 sieve specifications. Each standard mesh size has a corresponding micron value. For mesh numbers not in the standard table, linear interpolation between adjacent standard mesh sizes provides an approximate micron value.
What is the relationship between mesh and micron?
Mesh and micron have an inverse relationship: as mesh number increases, micron size decreases. A 4 mesh screen has 4750 micron openings, while a 400 mesh screen has only 38 micron openings. This inverse relationship means higher mesh numbers filter finer particles.
What industries use mesh to micron conversion?
Mesh to micron conversion is essential in industries like pharmaceuticals (powder sizing), mining and minerals (ore grading), food processing (flour and spice grinding), construction (aggregate sizing), ceramics, and water filtration where precise particle size distribution matters.
Is there a standard for mesh sizes?
Yes, mesh sizes are standardized under ASTM E11 (US) and ISO 3310-1 (international). These standards define the exact opening sizes for each mesh number. The US standard sieve series uses mesh numbers from 3.5 to 400, with corresponding micron sizes precisely defined.
Can this converter handle non-standard mesh numbers?
Yes, the converter handles non-standard mesh numbers by interpolating between the nearest standard mesh sizes. For example, if you enter mesh 90, the converter interpolates between 80 mesh (180 microns) and 100 mesh (150 microns) to provide an estimate of about 165 microns.
What is the range of mesh sizes supported?
This converter supports mesh sizes from 4 to 400, covering the full range of standard ASTM E11 sieve sizes. This includes coarse screens (4-20 mesh), medium sieves (25-100 mesh), and fine sieves (120-400 mesh) used for everything from gravel to fine powders.
