#### What is Standard Wire Gauge SWG and its use?

The thickness of a wire is often given as a Standard Wire Gauge, or SWG. This is number from 0000000 or 7/0 (thickest) to 50 (thinnest). The gauge of most wire used in electronics is between 20 and 30.

Is SWG the same as AWG?

The AWG is used for non-ferrous metals, while the SWG is commonly used for ferrous metals. SWG wires tend to bigger than AWG of the same gauge. The SWG system measures wires in inches, while the AWG measures them using the metric system of measurement. The number of steps in each wire gauge system is different.

### What does SWG stand for in wire gauge?

SWG = Standard or Sterling Wire Gauge, a British wire measurement system. BWG = Birmingham Wire Gauge, an old British wire measurement system that was widely used throughout the world. Cir Mils or CMA = Circular Mil Area which is equal to 1/1000 (0.001) of an inch in diameter or 0.000507 MM.

#### How to calculate SWG to mm cross sectional area?

SWG to mm conversion calculator Wire cross sectional area calculation The n gauge wire’s cross sercional area A n in square millimeters (mm 2) is equal to pi divided by 4 times the square wire diameter d in millimeters (mm): An (mm2) = (π/4)× dn2
