Electrical Power Conversion

If you have an appliance that is rated in Amps (current) but you want to know how much power it uses in Watts (to size a generator or solar panel), you need to know your local voltage.

Watt's Law

The formula is simple: Watts = Amps × Volts. In North America, standard wall outlets are 120V. In Europe, they are 230V.
