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.
So 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
What is the power consumption in watts when the energy consumption is 15 watt-hour for time duration of 4 hours?
P = 15 Wh / 4 h = 3.75 W
What is the power consumption in watts when the energy consumption is 25 watt-hour for time duration of 4 hours?
P = 25 Wh / 4 h = 6.25 W
What is the power consumption in watts when the energy consumption is 25 watt-hour for time duration of 4 hours?
P = 25 Wh / 4 h = 3.75 W
What is the power consumption in watts when the energy consumption is 35 watt-hour for time duration of 4 hours?
P = 35 Wh / 4 h = 8.75 W
