The Electrical Power calculator computes the power based on Ohm's Law using electrical potential or voltage (V) and current (I).
INSTRUCTIONS: Choose units and enter the following:
Electrical Power: The calculator returns the electrical power in watts. However, this can be automatically converted to other power units via the pull-down menu.

Power is most commonly measured in watts (W). One watt is equal to one joule per second (1 W = 1 J / 1 s). Power is also measured in horsepower (hp) where 1 horsepower equals 745.7 watts. Power is also measured in heat energy transfer as BTUs per hour (BTU/h).
