Amps to Watts Calculator
Convert amps to watts using current and voltage (W = A × V).
Formula
W = A × V
- W
- Power, in watts
- A
- Current, in amps
- V
- Voltage, in volts
What this calculator does
Converts a current reading in amps to power in watts at a given voltage.
Use cases
- Find the wattage of a load from a measured current
- Estimate energy usage from a circuit's current draw
- Check a nameplate wattage against a measured current
