1 J = 2.7778e-7 kWh
Full precision:2.778e-7 kWh
Step-by-Step Solution
To convert 1 joules to kilowatt-hours, we divide by 3600000 because one kilowatt-hour equals exactly 3600000 joules.
1 kilowatt-hour = 3600000 joules
Since there are 3600000 joules in every kilowatt-hour, we divide our value by this factor:
1 ÷ 3600000 = 2.7778e-7 kilowatt-hours
So 1 joules = 2.7778e-7 kilowatt-hours.
Quick check: 2.7778e-7 × 3600000 = 1 joules
