How to 转换 energy in kilowatt-hour (kWh) to 电气 power in watts (W).
You can 计算 watts from kilowatt-hour and hours. You can't 转换 kilowatt-hour to watt unit since kilowatt-hour and watt units represent different quantities.
The power P in watts (W) is equal to 1000 times the energy E in kilowatt-hour (kWh), divided by the 时间 period t in hours (hr):
P(W) = 1000 × E(kWh) / t(hr)
So
watt = kilowatt-hour / hour
or
W = 1000 × kWh / h
求 the power consumption in watts when the energy consumption is 15 kilowatt-hour for 时间 duration of 3 hours
P = 1000 × 15 kWh / 3 h = 5000 W
