How to Convert Kilowatt-Hours to Watts
A watt (W) is a measure of power, while a kilowatt-hour (kWh) is a measure of energy equivalent to 1,000 watt-hours, or 1,000 watts of power for 1 hour. So, to convert kilowatt-hours to watts, multiply the energy in kilowatt-hours by 1,000 to find the energy in watt-hours, then divide by the time in hours.
kWh to Watts Formula
Use this formula to convert watts to kilowatt-hours:
P(W) = E(kWh) × 1,000 / T(hrs)
Thus, the power P in watts is equal to the energy E in kilowatt-hours times 1,000, divided by the time T in hours.
For example: let’s find the average watts of power for 3 kWh of energy used in 6.5 hours.
P(W) = 3 kWh × 1,000 / 6.5 hrs
P(W) = 3,000 Wh / 6.5 hrs
P(W) = 461.54 W
So, 3 kilowatt-hours of energy over 6.5 hours will consume 461.54 watts of power.
If you don’t multiply the top half of the fraction by 1,000, then the formula will convert the energy to kilowatts.
