DETERMINING WIRE DIAMETER ABROAD. AWG AND SWG
When selecting wire products, it is necessary to determine the wire diameter, as it is often indicated in the form of gauge numbers in English literature.
There are two standards:
- AWG — American Wire Gauge — American standard;
- SWG — Standard Wire Gauge — British standard.
When determining the wire diameter, attention should be paid to this classification.

Mesh is the number of holes per 1 linear inch (25.4 mm). When calculating the actual hole size, the diameter (or gauge) must be considered.
The conversion of "mesh" to particle sizes (mm) can be done according to various classifications and sources: BSS, Tyler, US, etc.
