# AWG Wire Gauge Calculator

> AWG Wire Gauge Calculator is a paid API for AI agents from electronics-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-25).

Returns AWG copper wire diameter, cross-sectional area, resistance per km, and optionally calculates voltage drop and power loss over a given run.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability awg-wire-gauge-calculator-b98880f7
```

Example prompt: What's the diameter and resistance per km of AWG 12 copper wire, and what would the voltage drop be over a 25-metre run carrying 10 amps from a 120V supply?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
