**Category:** Education

## Quick Answer

Convert electric power in watts to current in amperes. Enter the wattage, voltage, and phase system to compute amps.

## Definition

A watts to amps calculator computes the electrical current flow rate in amperes based on the total power consumption in watts and the circuit voltage. By dividing power by voltage (and adjusting for power factor in single-phase and three-phase AC systems), it provides the exact current load. This calculation is crucial for determining fuse ratings, selecting conductor wire sizes, and planning appliance installations.

## How to Use

1. **Choose current type** — Select DC, AC single-phase, or AC three-phase configuration.
2. **Enter values** — Input the power in watts and the operating voltage in volts.
3. **Calculate** — View the estimated current in amperes along with safety recommendations.

## Disclaimer

This calculator provides estimates for educational and planning purposes. Always consult a qualified professional for specific advice on financial, medical, legal, or other regulated decisions.
