Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about 745.7 watts, and the metric horsepower as in "cv" or "PS" which is approximately 735.5 watts. The electric horsepower "hpE" is exactly 746 watts, while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year.
Roughly equivalent to the normal sustained power output of one horse – however the maximum power of a horse is much more than one horsepower. [8]: 253 A metric horsepower equals approximately 735.5 watts, [36] and an imperial horsepower (or imperial horsepower) equals approximately 745.7 watts. [37] Horse racing horse racing
Chart illustrating the increase in height of racehorses, from 14 hh (142 cm) in 1700 to 15. 2 + 1 ⁄ 2 hh (159 cm) in 1900. Today the hand is used to measure the height of horses, [2] ponies, and other equines. It is used in the US and also in some other nations that use the metric system, such as Australia, New Zealand, Canada, Ireland and ...
Horses are used to measure distances in horse racing – a horse length (shortened to merely a length when the context makes it obvious) equals roughly 8 feet or 2.4 metres. Shorter distances are measured in fractions of a horse length; also common are measurements of a full or fraction of a head, a neck, or a nose. [10]

One horsepower is the power needed to lift 75 kilograms (average weight of an person) by 1 metre (3.28 feet) within 1 second. The metric horsepower is equivalent to approx. 735.5 watts . Français : Illustration de la définition d'un cheval vapeur (ch)
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.
The British imperial units and U.S. customary units for both energy and work include the foot-pound force (1.3558 J), the British thermal unit (BTU) which has various values in the region of 1055 J, the horsepower-hour (2.6845 MJ), and the gasoline gallon equivalent (about 120 MJ).
