How does the Watts to Amps Calculator work?

Amps = Watts ÷ Volts (DC circuits) Then: Amps = Watts ÷ (Volts × Power Factor) (AC circuits) Then: Standard voltages: 120V (US), 230V (UK/EU), 240V (AU) Then: Power factor for resistive loads = 1.0.

Can you give an example of how to use the Watts to Amps Calculator?

Example: Input 2400W appliance at 240V gives a result of 10 amps.

Is the Watts to Amps Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

Electrical Converter

Watts (W)

A watts to amps converter calculates electrical current from power and voltage using Ohm's law. It is used for sizing circuit breakers, fuses, and cables for electrical installations.

Symbol	Name	Unit	Description
W	Power	W	Electrical power in watts
V	Voltage	V	Electrical potential difference in volts
A	Current	A	Electrical current in amperes
PF	Power factor	(dimensionless)	AC circuits only; typically 0.8–1.0

Appliance	Watts	Amps at 240V
LED Bulb	10W	0.04A
Laptop	65W	0.27A
Fridge	150W	0.63A
Washing Machine	2000W	8.3A
Electric Oven	3000W	12.5A
EV Charger	7400W	30.8A
