Frequently Asked Questions
How does Aluminum to Copper conversion work?
Aluminum has higher electrical resistivity than copper. To match copper's current carrying capacity (ampacity), an aluminum conductor requires approximately 1.6× the cross-sectional area (Target Area = Input Area × 1.6). Our app uses standard IEEE / IEC electrical conductivity formulas.
What is the difference between SWG and AWG?
SWG (Standard Wire Gauge) is the British standard commonly used in the UK, India, Bangladesh, and Europe. AWG (American Wire Gauge) is the North American standard primarily used in the USA and Canada. The app allows you to convert between mm, mm², SWG, and AWG seamlessly.
Why does the app suggest "For motor winding, consider one size thicker"?
When rewinding electric motors, slot space, thermal dissipation, and insulation varnish affect performance. Choosing the nearest thicker gauge ensures the motor runs cooler and prevents overheating under heavy continuous loads.
Does the app work offline?
Yes! All wire conversion formulas and standard wire gauge lookup tables run completely offline on your device without an internet connection.
