The horse-power was first used as a unit by James Watt in the early 19th century when he was trying to sell his steam engines to people who up till then had only used horses for things like pumping water out of mines.
He cheated a bit by using the scrawniest horse he could find to compare his engines with. So an actual horse can usually deliver rather more than one horse power (746W).
Despite this bit of chicanery, Watt's name is immortalised as the SI unit of power. Who said that cheats never prosper?
