WIRE CLOTH TERMINOLOGY ACCORDING TO ISO 9044

Aperture width “w’ is the distance between two adjacent warp or weft wires, measured in the project plane at the mid-positions. Wire diameter “d” is the diameter of the wire in the woven cloth. (wire diameter may be altered slightly during the weaving process.) Pitch “p’ is the distance between the middle point of two adjacent wires or the sum of the aperture width “w” and wire diameter “d”.
Warp: All wires running lengthwise of the cloth as woven.
Weft: All wires running across the cloth as woven.The number of apertures per unit length “n” is the number of apertures which are counted in a row one behind the other for a given unit length. The unit length may be 1 cm, 1 dm, Inch or any other unit of length. (The number of apertures with a length of 25.4 mm is designated as “Mesh”.)
Mesh = number of apertures per English inch = 25,4 ÷ “p’
n/cm = number of apertures per cm = 10 ÷ “p’
n/cm2 = number of apertures per cm2 = (10 ÷ “p”)2 Open screening area, Oa%: The percentage of the area of all the apertures in the total screening surface or the ratio of square of the nominal aperture width “w” and the square of the nominal pitch “p’ = “w” + “d", rounded to a full percentage value: Oa% = 100 . (“w”2 ÷ “p”2)
Type of weave is the way in which the warp and weft wires cross each other. Weight “G” of the steel wire cloth screen section in kg per m2.
G = (12,7 x “d”2) ÷ “p’
G = Mesh x “d”2/2

The Weaven types For Wire mesh and filter question information :
What does mesh size mean?
Figuring out mesh sizes is simple. All you do is count the number of openings in one inch of screen (in the United States, anyway.) The number of openings is the mesh size. So a 4 mesh screen means there are four little squares across one linear inch of screen. A 100 mesh screen has 100 openings, and so on.  As the number describing the mesh size increases, the size of the particles decreases. Higher numbers equal finer material. Mesh size is not a precise measurement of particle size.
How fine do screens get?
That depends on the wire thickness. If you think about it, the finer the weave, the closer the wires get together, eventually leaving no space between them at all. For this reason, beyond 325 mesh particle size is usually described in “microns.”
What is a micron?

A micron is another measurement of particle size. A micron is one-millionth of a meter or one twenty-five thousandth of an inch.
