Amps to kW Calculator
Convert amps to kilowatts using current and voltage (kW = A × V ÷ 1000).
Formula
kW = (A × V) ÷ 1000
- kW
- Power, in kilowatts
- A
- Current, in amps
- V
- Voltage, in volts
What this calculator does
Converts a current reading in amps to power in kilowatts at a given voltage.
Use cases
- Find the kW rating of a load from a measured current
- Estimate demand load in kilowatts from circuit amperage
- Cross-check a load schedule entry against measured current
