How to convert watt-hours to watts

How to convert energy in watt-hour (Wh) to electric power in watts (W).

You can calculate watt from watt-hour and hours, but you can't convert watt-hour to watt units, since watt-hour and watt units represent different quantities.

 

Watt-hour to watts calculation formula

The power P in watts (W) is equal to the energy E in watt-hour (Wh), divided by the time period t in hours (h):

P(W) = E(Wh) / t(h)

So

watts = watt-hours / hours

or

W = Wh / h

 

Example

What is the power consumption in watts when the energy consumption is 15 watt-hour for time duration of 3 hours?

P = 15 Wh / 3 h = 5 W
