How to Convert Kilowatt-Hours to Watts
A watt, expressed as W, is a measure of power while a kilowatt-hour 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.
Use this formula to convert watts to kilowatt-hours:
watts = (kWh × 1,000) ÷ hrs
For example: let’s find the watts of power for 3kWh of energy used in 6.5 hours.
watts = (3 kWh × 1,000) ÷ 6.5 hrs
watts = 3,000 ÷ 6.5 hrs
watts = 461.54 W
