Solved Examples for watts to kilowatt-hours conversion
Example 1: Find energy used in kWh by 10 watt LED during time duration of 4 hours.
Solution: kWh = watts * time / 1000 = 10 * 4 / 1000 = 0.04 kWh
Example 2: Find power consumed by 2200 watts Heater used for 30 minutes.
Here time is in minutes. So time in hours = 30/60 = 0.5
kWh = watts * time/1000 = 2200*0.5/1000 = 1.1 kWh
Example 3: Find the power consumed by 5000 watt amplifier during 300 seconds.
Solution: Here time is in seconds. So time in hours = 300/3600 = 0.0833 hours
kWh = 5000 * 0.0833 / 1000 = 0.416 kWh
