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.
Watt-hours (Wh)
Definition
A watt-hour (Wh) is a unit of energy equal to the work done by one watt of power sustained for one hour. It equals 3,600 joules.
History
The watt-hour emerged with the development of electrical power systems in the late 19th century. It provided a practical way to measure and bill for electrical energy consumption.
Current use
Watt-hours are used for small battery capacities (e.g., phone batteries, portable electronics) and as a base unit for kilowatt-hours used in household electricity metering.
