Etymologically, the entry records: From horse + power: 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 hou… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is horsepower, spelled H-O-R-S-E-P-O-W-E-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

Etymology

From horse + power: 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).
