How amp to kW 220V calculator works
The amp to kW 220V calculator converts current into kilowatts (kW) on a 220 V supply with 3 inputs: current, power factor and phase. Each amp at 220 V and power factor 1 adds 0.22 kW.
P = I × 220 × PF / 100010 A at 220 V and PF 1 gives 2.2 kW. The line chart plots kW against amps at 220 V and marks the selected current.
Amp to kW 220V formula
The amp to kW 220V formula is P(kW) = I(A) × 220 × PF / 1,000 for single phase. There are 3 formulas at 220 V: single phase, three phase and kW per amp.
Single phase 220 V
P = I × 220 × PF / 100010 A × 220 V / 1,000 = 2.2 kW
Three phase 220 V L-L
P = √3 × I × 220 × PF / 10001.732 × 10 A × 220 V / 1,000 = 3.81 kW
kW per amp
P per A = 220 × PF / 1000220 V × 1 / 1,000 = 0.22 kW per A
220 V single phase is used in more than 50 countries, including Bangladesh, China, Pakistan, Russia and Saudi Arabia, and 220 V line to line is a three-phase voltage in Brazil and the Philippines.
