Foramula of Opening(mm), Wire Diameter, and Mesh
A: Opening(mm)
d: Wire Diameter(mm)
M: Mesh
[[ Formula ]]
A = 25.4/M - d

¡ How to read and write Mesh, Particle Size(mm, microns)
- "+200mesh" means that particle size is larger/more coarse than 200mesh(or 74microns).
- "-200mesh" means that particle size is smaller/finer than 200 mesh(or 74 microns).
- ">74ƒÊm" means that particles size is larger than 74 microns(or 200 mesh).
- "<74ƒÊm" means that particles size is smaller than 74 microns(or 200 mesh).
