Calories (cal)
Definition
A calorie (cal), also known as a small calorie or gram calorie, is defined as the amount of heat energy needed to raise the temperature of one gram of water by one degree Celsius. It equals approximately 4.184 joules.
History
The calorie was first defined by French chemist Nicolas Clément in 1824. It was widely used in chemistry and physiology before the joule became the official SI unit of energy.
Current use
Small calories are used in chemistry and physics for heat measurements. In everyday language, 'calorie' often refers to the kilocalorie (kcal) when discussing food energy.
Ergs
Definition
An erg is a CGS (centimeter-gram-second) unit of energy equal to 10⁻⁷ joules. It represents the work done by a force of one dyne over a distance of one centimeter.
History
The erg was the standard energy unit in the CGS system, widely used in physics before the SI system gained dominance. It was introduced in the mid-19th century alongside other CGS mechanical units.
Current use
Ergs are still used in astrophysics and some branches of physics, particularly for describing stellar energy output, supernova energies, and spectroscopic measurements in legacy literature.
