How to Use This Calculator
- Select the wire gauge number from the dropdown (0-40). Lower numbers indicate thicker wire.
- Choose the material type (copper, aluminum, or iron) if applicable.
- Click the "Calculate" button to determine the wire diameter.
- The calculator displays the diameter in both inches and millimeters, as well as the circular mil value.
Understanding Wire Gauge
Wire gauge is a measurement system for wire diameter. In the American Wire Gauge (AWG) system, a lower gauge number means a thicker wire, while a higher gauge number means a thinner wire. The AWG system was developed to standardize wire sizes for electrical applications.
Why Use This Calculator?
- Electrical engineers and technicians need to select appropriate wire sizes for their applications.
- When working with electrical systems, it's important to match wire gauge with amperage capacity.
- This calculator helps convert between gauge numbers and actual dimensions.
- Circular mil is a unit of cross-sectional area used in electrical engineering.
