How amps to kW 230V calculator works
The amps to kW 230V calculator converts current into kilowatts (kW) on the 230 V single-phase supply with 2 inputs: current and power factor. Each amp at 230 V and power factor 1 adds 0.23 kW.
P = I × 230 × PF / 100013 A at 230 V gives 2.99 kW, just under a 3 kW kettle. The bar chart ranks the load against 8 household appliances.
Amps to kW 230V formula
The amps to kW 230V formula is P(kW) = I(A) × 230 × PF / 1,000. There are 3 formulas at 230 V: real power, apparent power and amps from kW.
Real power
P = I × 230 × PF / 100013 A × 230 V / 1,000 = 2.99 kW
Apparent power
S = I × 230 / 100016 A × 230 V / 1,000 = 3.68 kVA
Amps from kW
I = P × 1000 / (230 × PF)3 kW × 1,000 / 230 V = 13.04 A
IEC 60038 set 230 V as the standard low-voltage supply for Europe, the UK, Australia, India and most of Africa and Asia, at 50 hertz (Hz).

Amps to kW 230V equation
The amps to kW 230V equation is P = I × 230 × PF / 1,000, where 230 is the supply voltage in volts.
- P
- Real power in kW
- I
- Current in amperes (A)
- 230
- Supply voltage (V)
- PF
- Power factor
Power rises 0.23 kW for every amp at PF 1: 6 A gives 1.38 kW and 40 A gives 9.2 kW.
