Here's the simple formula we use to calculate power on a 1-phase AC circuit: P (kW) = I (Amps) V (Volts) 1,000 Basically, we just multiply amp by volts. The '1,000' factor is there to convert from W to kW; we want the resulting power to be in kilowatts. 1 kW = 1,000W. Compared to this, the 3-phase power formula is a bit more complex.
