Megajoules (MJ)

Definition

A megajoule (MJ) is a unit of energy equal to 1,000,000 joules (10⁶ J). It is used to express large-scale energy quantities.

History

The megajoule became commonly used with the growth of industrial energy measurement in the 20th century, particularly for fuel energy content and large engineering systems.

Current use

Megajoules are used to express the energy content of fuels (e.g., natural gas, gasoline), industrial process energy, and large-scale thermal systems in engineering and environmental science.

Kilowatt-hours (kWh)

Definition

A kilowatt-hour (kWh) is a unit of energy equal to 1,000 watt-hours or 3,600,000 joules. It represents the energy consumed by a 1,000-watt appliance running for one hour.

History

The kilowatt-hour became the standard billing unit for electricity with the widespread electrification of homes and businesses in the early 20th century. Power utilities worldwide adopted it for metering.

Current use

Kilowatt-hours are the universal unit for residential and commercial electricity billing. They are also used to measure electric vehicle battery capacity, solar panel output, and grid-level energy storage.
