How this service works
AWG copper wire: diameter, area and resistance per km, the nearest AWG for an area, and voltage drop over a run.
Output
Returns AWG gauge, wire diameter in mm and inches, cross-sectional area in mm², copper resistance in Ω/km and Ω/1000ft. If length, current and supply voltage are provided, also returns loop length, loop resistance, voltage drop in volts and as a percentage, and power loss in watts.
Example use cases
Home wiring voltage drop check
“I'm running AWG 14 copper wire 30 metres to a shed from a 240V panel carrying 15 amps — what's the expected voltage drop in volts and percent?”
Finding nearest AWG for cable spec
“I have a 4 mm² copper cable spec — what's the nearest AWG number, and what's its diameter and resistance per kilometre?”
Low-voltage DC power loss estimation
“I need to know the power loss and voltage drop for AWG 10 wire on a 50-metre one-way run in a 48V 20-amp solar system.”
Technical details
Endpoint
GEThttps://electronics-calc.x402tookit.com/wire-gauge?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need accurate copper wire properties (AWG lookup, area-to-AWG conversion, resistance) or need to calculate voltage drop and power loss for a DC or AC cable run. Prefer over manual lookup tables when an exact area-to-AWG match is needed or when voltage drop across a specific run length and current must be computed programmatically.
Side effects
- AWG number out of range (-3 to 40) returns an error or null values
- Providing neither awg nor areaMm2 yields no wire properties
- Voltage drop fields null if currentA or lengthM not supplied
- supplyV omitted means voltageDropPct will be null even if voltageDropV is present
