Summary
Birmingham Wire Gauge (BWG), also known as Stubs Iron Wire Gauge is a system of measurements describing thickness. BWG has been historically used to describe the outside diameter of small tubes and wires, as well as the wall thickness of some large tubes (such as those used within a shell and tube heat exchanger). This article presents length conversions for BWG values into metric and imperial units.
