I know that BHP is the measure of power of an engine. I realised that I have no idea how the number (for example 540 BHP) relates to the engine itself.

  • Does 1 HP mean one rotation of the crankshaft per a given time? Or is there some other way of defining it?

  • How do you define BHP?

  • Also, what is the difference between HP and BHP?
