Convert W to Wh (Watts to Watthours)

To convert W to Wh, you need to multiply the number of Watts by the number of hours:
First, fill in this box with your Watts:
Then fill in this box with the duration in hours and click on Calculate
Duration: hours
The formula is (W)*(h) = (Wh). For example, if you have 100 W for a duration of 2 hours, then the wattage is (100)*(2) = (200) Watts.
(Watthours is a measure of energy and watts is a unit of power. Power multiplied by time is enery).
