Electric power is measured in watts (W) or kilowatts (kW), the voltage is measured in volts (V) and the current is measured in amperes (amps). The relationships between these values can help you solve for the unknown value, such as, if you know the power, but need to find the amps. When you have three-phase power, you need to divide the result by the square root of three, or about 1.73, to accurately convert. In addition, you also have to know the voltage.

## Instructions

1. 1

Multiply the number of kW by 1,000 to convert to W. For example, if you have 2kW, multiply 2 by 1,000 to get 2,000W.

2. 2

Divide the number of W by the voltage. For example, if the voltage equals 120 V, divide 2,000 by 120 to get 16.67.

3. 3

Divide the result by 1.73 to find the amperes. Divide by 1.73 because of the three phases. Completing the example, divide 16.67 by 1.73 to get 9.63 amps.
