Volts to Watts Calculator
Volts to Watts Calculator
The Volts to Watts Calculator allows you to quickly convert electrical voltage and current into power. This is one of the most important calculations in electrical engineering, home energy usage, and electronics.
Whether you are working with DC circuits, single-phase AC, or three-phase systems, this calculator provides accurate and instant results.
Understanding Volts, Amps, and Watts
- Voltage (V): Electrical pressure
- Current (A): Flow of electricity
- Power (W): Energy consumption rate
Volts to Watts Formula
DC Formula
P = V × I
Single-Phase AC
P = V × I × PF
Three-Phase AC
P = √3 × V × I × PF
How to Use the Calculator
- Enter voltage (V)
- Enter current (A)
- Select system type (DC, single-phase, or three-phase)
- Enter power factor if needed
- Click calculate
Example
For a 230V system with 10A current:
DC: 230 × 10 = 2300 W
AC with PF 0.9:
230 × 10 × 0.9 = 2070 W
