kW to Volts Calculator – DC, AC Single Phase & Three Phase
Easily convert kilowatts (kW) to volts (V) for DC, AC single phase, and AC three phase circuits. Enter the power in kW, current in amps, and (for AC) the power factor to get the voltage instantly.
kW to Volts Formula
- DC: V (V) = 1000 × P (kW) ÷ I (A)
- AC Single Phase: V (V) = 1000 × P (kW) ÷ (PF × I (A))
- AC Three Phase (Line-to-Line): V (V) = 1000 × P (kW) ÷ (√3 × PF × I (A))
Example Calculations
- DC: 2.3kW, 10A → 1000 × 2.3 ÷ 10 = 230V
- AC 1-Phase: 1.84kW, 10A, PF 0.8 → 1000 × 1.84 ÷ (0.8 × 10) = 230V
- AC 3-Phase: 12.47kW, 20A, PF 0.9 → 1000 × 12.47 ÷ (1.732 × 0.9 × 20) = 400V
