How Many Amps Equal a Kilowatt?
Last Updated Mar 25, 2020 2:21:13 PM ET
Amps are a measure of electric current and kilowatts are a measure of electric power, so the two are not strictly interchangeable. This means that a third factor, voltage, must be accounted for in any conversion of amps to kilowatts.
The formula for converting amps, represented by A, into kilowatts, represented by kW, by way of voltage, represented by V, is: P(kW) = 1(A) ? V(V) / 1,000. This equation states that the total power output in kilowatts, P, is equal to 1 amp, multiplied by the dividend of a given voltage divided by 1,000. A flow of 9 amps, for example, at the standard U.S. house current of 110 V, is therefore equal to 0.99 kW.
