- For single-phase: kW = V × A × PF ÷ 1000
- For three-phase: kW = √3 × V × A × PF ÷ 1000
- For DC: kW = V × A ÷ 1000 (PF not used)
- kVA = kW ÷ PF (for AC). If PF = 0, kVA is not defined.
Easily convert electrical current (Amps) into power (kW) with our accurate Amps to kW calculator. Perfect for electricians, engineers, or anyone working with electrical circuits, this calculator supports single-phase AC, three-phase AC, and DC systems. Simply enter the voltage, current, and power factor (for AC), and instantly get your power in kilowatts (kW) and apparent power (kVA).
Formulas Used:
- Single-phase AC:
kW=V×A×PF1000\text{kW} = \frac{V \times A \times PF}{1000}kW=1000V×A×PF
- Three-phase AC:
kW=3×V×A×PF1000\text{kW} = \frac{\sqrt{3} \times V \times A \times PF}{1000}kW=10003×V×A×PF
- DC Circuits:
kW=V×A1000\text{kW} = \frac{V \times A}{1000}kW=1000V×A
- Apparent Power (AC only):
kVA=kWPF\text{kVA} = \frac{\text{kW}}{PF}kVA=PFkW
Key Features:
- Works for single-phase, three-phase, and DC circuits.
- Power factor handled automatically for AC circuits.
- Displays both kW and kVA for quick reference.
- Lightweight, single-page tool, no extra software required.
- Clean, light interface for all devices.
Use Cases:
- Electrical load planning for homes, offices, and industrial systems.
