Thermies (FR)

Definition

A thermie is a French unit of heat energy equal to 1,000 kilocalories, or approximately 4,184,000 joules. It was historically used in French engineering and heating systems.

History

The thermie was used in France and other French-speaking countries throughout the 20th century for industrial heating and energy calculations, before the widespread adoption of joules and kilowatt-hours.

Current use

The thermie is now largely obsolete but may still appear in older French engineering documentation, historical heating system specifications, and some regulatory texts.

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.
