Watts Amps Volts Calculator

Easy to use electrical power calculator for converting and calculating to and from Watts, Amps, Volts, kW or Power Factor (PF) AC and DC.

Supports AC Single-Phase, AC Three-Phase, and DC electrical calculations in 16 languages.

Supports dark mode and light mode themes.

Electrical calculations include AC 1-phase (single-phase), AC 3-phase (three-phase) and DC electrical calculations.

AC Single Phase Calculations:
- Calculate Watts.
- Calculate Amps.
- Calculate Volts.

AC Three Phase Calculations:
- Calculate kW.
- Calculate Amps.
- Calculate Volts.
- Power Factor (PF).

DC Calculations:
- Calculate Watts.
- Calculate Amps.
- Calculate Volts.

Electrical units are measured in the following:
Current (I) = Amps.
Power (P) = Watts (or kW).
Volts (V) = Voltage.

Simple, fast, and accurate — the electrical calculator you'll reach for every day.
