Energy Converter
Energy across joules, calories, kilowatt hours and BTU. The food calorie is a kilocalorie, so a 2,000 calorie diet is two million of the calories a physicist means.
Also called: kwh to joules, calories to kilojoules, btu converter.
Result
3,600
1 Kilowatt hour is 3,600 Kilojoule. The factor is 3,600, and the inverse is 0.0002777778. The table below gives the same value in every energy unit at once.

Method and background
How this is calculated
Everything is held against the joule. The naming collision is worth knowing: the calorie on a nutrition label is a kilocalorie, a thousand times the thermochemical calorie used in physics, and it is often capitalised as Calorie to mark the difference. A kilowatt hour is simply a thousand watts sustained for an hour, which is 3.6 million joules.
result = value * factor_from / factor_to- k
