The number of openings is determined by mesh count and the opening size is determined by the micron rating.
Mesh to micron conversion does not have a standard formula, however we can roughly convert by multiplying 14900 by the specified mesh size (micron = 14900/mesh).
The mesh opening profile will normally be defined as a mesh count when the openings are measured in inches or millimetres.

The measurement is changed to microns once the opening dimensions are less than one millimetre.

The openings of coarser weaves, which are frequently square meshes, are described by mesh count.
The number of holes in a filter per unit area is called the mesh size. One square inch is the standard area in the United States.
For example,
Consider a piece of wire mesh that is marked as 50 mesh. This indicates that if you were to count the openings in the mesh, there would be 50 in both the horizontal and vertical directions.
Mesh count regulates the maximum flow velocity that the mesh allows since it shows how many apertures there are in a particular weave.
Inadequate mesh implementation can lead to excessive pressure formation in the structure, which can raise stress and promote wear and tear.
The openings of a finer weave, usually filter cloth, are described by a micron rating
Wire mesh apertures less than one millimetre are designated by a micron rating. It is the exact separation of any opening’s wires from one another.
As a result, what may and cannot pass through woven wire mesh is closely correlated with its micron rating.
The size of a hole can be described by its micron rating, which also defines the spacing between its wires. This indicates that what may and cannot pass through woven wire mesh is closely correlated with the mesh’s micron rating.
The possibility of undesired particles getting through the mesh increases when a micron value is used that is too high. Utilising a micron rating that is too small raises the possibility of blinding
