Horsepower

 

an obsolete subsidiary unit of power. It was first introduced in the 18th century and continues in use in various branches of technology, mainly in automotive engineering. Horsepower is designated as ls. (Russian, loshadinaia sila), PS (German, Pferdestärke), CV (French, cheval-vapeur), and HP or hp (English). In the USSR and certain other countries 1 hp = 75 kilograms-force per m/sec ≈ 735.5 watts (W); in the USA and Great Britain 1 hp = 550 ft.lb/sec ≈ 745.7 W.
