Watt’s in a name? Units of power and energy (2019)

unapi

The origins and adoption of the units of power and energy watt and joule are examined, along with their relationships to the achievements of their namesakes, James Watt and James Prescott Joule. The watt and joule came about as part of a group of practical electrical units named and defined in the second half of the nineteenth century. The development of that system and its relationship to the French revolutionary metric system and the current Système International (SI) is outlined. William Thomson (later Lord Kelvin) and the Siemens brothers had important parts in the story; their roles and the units names after them are also described.
