Kilowatt-hour

Definition: A kilowatt-hour (symbol kWh) is a unit of energy equal to one kilowatt (1,000 watts) of power sustained for one hour. It is a standard unit for measuring electrical energy consumption.

History/origin: The kilowatt-hour became widely adopted with the expansion of electrical grids and the need for a practical unit to measure household and industrial energy usage.

Current use: Kilowatt-hours are the standard unit used by utility companies to bill consumers for electricity usage. It's also used to specify the energy output of power plants and the energy consumption of large appliances.

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.
