How the calculation works
Convert an AWG number to wire diameter and cross-sectional area. The tool converts the form units and presents the result using readable engineering notation.
d(mm) = 0.127 × 92^((36−AWG)/39)
Example
AWG 18 is about 1.02 mm in diameter and 0.82 mm² in area.
How to interpret the result
- AWG number decreases as wire diameter increases.
- Cross-sectional area helps compare metric and American wire sizes.
- Allowable current also depends on insulation, temperature, bundling and installation.
Limitations and safe use
The result uses a simplified model. Check tolerance, temperature, absolute ratings and the component datasheet.
FAQ
Is the result saved?
The latest result may be stored locally in this browser, but it is not sent to LutujTo.
Can I use the result in a project?
Yes, but select a real component with margin and confirm its ratings in the datasheet.
