A to kW (Amps to kW — Amper to kiloWatts) online calculator

Enter the amperage in A (Amps):

Enter voltage in V (Volts):

(the most common voltage standard is 230 and 110 volts)

Power, P, in kW (kilowatts) is:

0.00kW

How to calculate the power in kW, if we know the amperage?

You can calculate using the formula:

P = I х U / 1000, where

I is the current in amperes (A);

P is the power in kilowatts (kW);

U is the voltage in volts (V).

1000 is the conversion factor from watts to kilowatts.

Thus, to get kilowatts from amperes, you need to multiply the amperes by the voltage in volts and divide by 1000.

P=kW = Amps * V / 1000

For example, convert 16 amperes to kilowatts.

If the standard voltage in electrical networks is 230 volts, then

P = I х U / 1000 = 16*230/1000 = 3,68 kW.

If the standard voltage in electrical networks is 110 volts, then

P = I х U / 1000 = 16*110/1000 = 1,76 kW
