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.

Electronvolts (eV)

Definition

An electronvolt (eV) is a unit of energy equal to the amount of kinetic energy gained by a single electron when accelerated through an electric potential difference of one volt. It equals approximately 1.602 × 10⁻¹⁹ joules.

History

The electronvolt emerged in the early 20th century with the development of particle physics and quantum mechanics. It provided a practical unit for describing atomic and subatomic energy scales.

Current use

Electronvolts are the standard unit in particle physics, nuclear physics, semiconductor physics, and quantum chemistry for expressing binding energies, photon energies, and particle masses.
