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
