Is Gauge Accepted in China?

GA or Gauge was accepted at the very beginning as the measurement of the cross-sectional area of a wire in particular in the North America though it is later introduced widely as a kind of measurement the thickness. Obviously Gauge is not a preferable / normal unit of measurement though it is known by very few professionals or persons dealing with the foreign customers. In this regard, to avoid further misunderstanding it is recommended that one should use “mm” or “inch” which is more accepted in China while dealing with the Chinese counterparts / partners or at least use two different units at the same time, i.e. 3 Ga. (0.2391 inch) in measuring the thickness of standard steel.
