How to distinguish the mesh number of the filter? And how to judge whether the filter screen is standard when using it?

The general definition refers to the number of meshes in the area of 1 inch * 1 inch, that is, the number of meshes that materials can pass through is defined as: for example, 200 meshes means that materials can pass through a 200-mesh screen in the area of 1 inch * 1 inch. By analogy, the larger the mesh number, the finer the material particle size, and the smaller the mesh number, the larger the material particle size.

Mesh: 4.75 mm ―― Standard mesh: 4 mesh.

Mesh: 4.00 mm ―― Standard mesh: 5 mesh.

Mesh: 3.35 mm ―― Standard mesh: 6 mesh.

Mesh: 2.80mm ―― Standard mesh: 7 meshes.

Mesh: 2.36 mm ―― Standard mesh: 8 mesh.

Mesh: 2.00 mm-standard mesh: 10 mesh.

Item:1.70mm-standard item: 12 item.

Item:1.40mm-standard item: 14 item.

Items:1.18mm-standard items: 16 items.

Item: 1.00 mm-standard item: 18 item.

Mesh: 0.850 mm ―― Standard mesh: 20 mesh.

Mesh: 0.7 10/0mm-standard mesh: 25 meshes.

Mesh: 0.600 mm ―― Standard mesh: 30 mesh.

Mesh size: 0.500 mm-standard mesh: 35 mesh.

Mesh size: 0.425mm ―― standard mesh: 40 mesh.

Mesh size: 0.355 mm-standard mesh: 45 mesh.

Mesh: 0.300mm ―― Standard mesh: 50 mesh.

Mesh size: 0.250 mm-standard mesh: 60 mesh.

Mesh: 0.212mm-standard mesh: 70 mesh.

Mesh: 0.180mm-standard mesh: 80 mesh.

Item: 0.150mm-standard item: 100 item.

Item: 0.125mm-standard item:125mm.

Item: 0.106mm-standard item: 140 item.

Mesh: 0.090 mm-standard mesh: 170 mesh.

Mesh: 0.0750 mm ―― Standard mesh: 200 mesh.

Mesh size: 0.0630mm-standard mesh: 230 mesh.

Mesh size: 0.0530mm-standard mesh: 270 mesh.

Mesh size: 0.0450 mm-standard mesh: 325 mesh.

I almost forgot to mention: the above refers to the American standard (used in China). If it's Taylor, the size will be different.
