How to Convert Amps to Watts

How to convert current in amps (A) to power in watts (W).

Amps to watts calculation formula

The power P in watts is equal to the current I in amps, times the voltage V in volts:

P_(W) = I_(A) × V_(V)

So

watt = amp × volt

Or

W = A×V

Example

What is the power consumption of an electrical circuit that has current flow of 3 amps and voltage supply of 15 volts?

P = 3A × 15V = 45W
