horsepower

Etymology

 * the unit was originally defined as the amount of power that a horse could provide.

Both non-metric and metric units of power were derived from effectively identical measurements of the power a draught horse could sustain over several hours, with the difference in watts solely due to different rounding errors to express that power in round numbers in the original non-SI units (ft·lbf/min and kgf⋅m/s respectively).

Noun

 * 1)  Power derived from the motion of a horse.
 * 2) A nonmetric unit of power (symbol hp) with various definitions, for different applications. The most common of them is probably the mechanical horsepower, approximately equal to 745.7 watts.
 * 3) * 2012 March 22nd, David Blockley, Engineering: A Very Short Introduction (309),, ISBN 9780199578696, chapter 2: “The age of gravity – time for work”, page 20:
 * In the past, before the widespread adoption of SI units, the work that engines were capable of doing was compared with the work that horses could do – hence the term ‘horsepower’. Various people came up with various equivalencies, but the modern agreed definition is that 1 horsepower is 746 joules per second or 746 watts.
 * 1) A metric unit (symbol often PS from the German abbreviation), approximately equal to 735.5 watts.
 * 2)  Strength.
 * 1)  Strength.
