Electrical Conversion Calculator – Volts, Amps, Watts, kWh
Easily convert between electrical units with this free online tool. Convert volts to amps, watts to volts, kilowatt-hours to watt-hours, and more with instant, accurate results.
Common Electrical Conversions
- Volts to Amps: I = P/V
- Volts to Watts: P = V × I
- Amps to Watts: P = V × I
- Watts to Volts: V = P/I
- Watts to Amps: I = P/V
- kWh to Wh: Wh = kWh × 1000
- Wh to kWh: kWh = Wh ÷ 1000
- Ah to kWh: kWh = Ah × V ÷ 1000
- kWh to Ah: Ah = kWh × 1000 ÷ V
Common Electrical Units
- Voltage (V): Electrical potential difference
- Current (A): Flow of electrical charge
- Power (W): Rate of energy transfer
- Energy (kWh/Wh): Total energy consumed
- Capacity (Ah): Battery capacity
Examples
- 120V, 10A = 1200W
- 1000W, 120V = 8.33A
- 1kWh = 1000Wh
- 100Ah, 12V = 1.2kWh
