BHP vs. HP: What's the difference?

BHP, brake horsepower, and HP, horsepower, are used to refer to the power of an engine. HP measures each foot-pound per second that the engine can move (one horsepower is 550 foot-pounds per second). BHP measures how much of this power is available by the engine for driving machinery other than itself—in other words, the horsepower minus what it takes to run the engine.
