Awg To Mm2 Formula
The following formula is used to calculate the conversion from American Wire Gauge (AWG) to square millimeters (mm²) for a solid round conductor.
mm² = 0.012668 * 92^{((36-AWG)/19.5)}Variables:
- mm² is the cross-sectional area in square millimeters
- AWG is the American Wire Gauge number
To calculate the cross-sectional area in square millimeters, subtract the AWG number from 36. Divide the result by 19.5 and raise 92 to the power of this quotient. Multiply the result by 0.012668.

What is Awg To Mm2?
AWG to mm2 is a conversion between an AWG wire size (a standardized gauge number) and a metric cross-sectional area value in square millimeters (mm²). AWG stands for American Wire Gauge, a standard used primarily in North America, while mm2 stands for square millimeters, a metric unit used internationally. The larger the AWG number, the smaller the wire diameter and cross-sectional area; conversely, a larger cross-sectional area (mm²) corresponds to a smaller AWG number.
How to Calculate Awg To Mm2?
The following steps outline how to calculate the cross-sectional area in square millimeters (mm²) using the formula for AWG to mm² conversion:
- First, determine the AWG number.
- Next, subtract the AWG number from 36.
- Divide the result by 19.5.
- Raise 92 to the power of the quotient obtained in the previous step.
- Multiply the result by 0.012668.
- Finally, calculate the cross-sectional area in mm².
- After inserting the AWG number and calculating the result, check your answer with the calculator above.
