## Quick Answer

Convert electrical current in amperes to power in watts. Enter current, voltage, and power factor to calculate watts instantly.

## Definition

An amps to watts calculator is an electrical engineering utility that computes electric power in watts based on the current drawing rate in amperes and the voltage of the circuit. The tool handles DC systems using the direct product of current and voltage, and AC systems by factoring in the electrical power factor and phase configurations (single-phase vs. three-phase). Electricians and homeowners use it to size circuits and avoid overloading breakers.

## How to Use

1. **Choose current type** — Select DC, AC single-phase, or AC three-phase configuration.
2. **Enter values** — Input the current in amperes and the circuit voltage in volts.
3. **Calculate** — View the calculated power in watts along with the specific formula used.
