Mesh refers to the number of screen holes per square inch. For example, a 50-mesh screen means 50×50 holes per square inch, while a 500-mesh screen has 500×500 holes, so the higher the mesh number, the smaller the pore size and the greater the number of holes. The mesh number is also used to measure the particle size that can pass through the screen. The higher the mesh number, the smaller the particle size.

Since wires of different thicknesses are used when weaving screens, there are differences in opening rates, so different countries adopt different standards. The United States, Britain and Japan have their own standards. The American and British standards are similar, but the Japanese standards are quite different. In China, we use the American standard, so we can use the formula mentioned earlier to calculate it.
