SWG to mm conversion
The SWG to mm and mm2 conversion calculator simplifies the process of converting Standard Wire Gauge (SWG) measurements to millimeters (mm) and square millimeters (mm2). This user-friendly tool provides accurate conversions by simply entering the SWG value. Additionally, a conversion chart is available for reference. To convert SWG to mm, multiply the SWG value by 0.464. To convert SWG to mm2, square the converted mm value.
Wire cross sectional area calculation
The n gauge wire's cross sercional area An in square millimeters (mm2) is equal to pi divided by 4 times the square wire diameter d in millimeters (mm):
An (mm2) = (π/4)×dn2
