The AWG to mm² Calculator allows you to easily convert the American Wire Gauge (AWG) value into square millimeters (mm²). This conversion is essential for various applications, especially in electrical engineering and wiring, where the size of the wire determines its conductivity and suitability for specific purposes. By knowing the wire’s cross-sectional area in mm², you can select the appropriate wire size for different electrical tasks. This calculator provides a fast and accurate way to make that conversion, based on the formula relating AWG to mm².
Formula
The formula to convert AWG to mm² is:
mm² = 0.0005067 * 92 ^ ((36 – AWG) / 39)
Where:
- AWG is the American Wire Gauge value (the wire’s gauge).
- mm² is the wire’s cross-sectional area in square millimeters.
This formula helps translate the AWG value into the wire’s size in terms of area, which is crucial when assessing how much current the wire can safely carry.
How to use
- Enter the AWG value: Input the wire’s gauge (AWG value) into the provided field.
- Click “Calculate”: After entering the AWG value, click the “Calculate” button to perform the conversion.
- View the result: The calculator will display the result in mm² (square millimeters), indicating the wire’s cross-sectional area.
Example
For instance, let’s convert an AWG value of 14 to mm²:
- AWG = 14
- Using the formula:
mm² = 0.0005067 * 92 ^ ((36 – 14) / 39) - The result will be approximately 2.08 mm².
This means that a wire with an AWG of 14 has a cross-sectional area of approximately 2.08 square millimeters.
FAQs
