How to convert Wh to Watts

Wh to Watts calculation formula

P(W) = E(Wh) / t(h)

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


W = Wh / h
watt = watt-hour / hour

For example:

Energy (E) = 45Wh
Time period (t) = 10h

Power (P) = 45Wh / 10h = 4,5W
