Watt-hour [Wh] to Kilojoule [kJ] Converter
How to Convert Watt-hour to Kilojoule
1 Wh = 3.6 kJ
1 kJ = 0.2777777777777778 Wh
Example: convert 10 Wh to kJ:
10 Wh = 10 x 3.6 = 36 kJ
Watt-hour
Definition: A watt-hour (symbol Wh) is a unit of energy equal to one watt of power sustained for one hour. It is commonly used to measure electrical energy consumption.
History/origin: The watt-hour is derived from the watt, the SI unit of power, and the hour, a unit of time. It was developed alongside the increasing use of electricity in the late 19th and early 20th centuries.
Current use: Watt-hours are commonly used to measure the energy capacity of batteries, the energy consumption of household appliances, and the amount of electricity generated or consumed by power plants and consumers.
Kilojoule
Definition: A kilojoule (symbol: kJ) is equal to 1000 joules. It's a unit of energy.
History/origin: Based on the joule, using the SI prefix 'kilo-' to denote a factor of one thousand.
Current use: Commonly used to express the energy content of food, fuels, and other substances when the joule would be impractically small. Also used in thermodynamics and other areas of physics and engineering.
