One horsepower is equivalent to 746 watts ( = joules of energy per second) or 550 ft.lb (force) of work per second.

<><><>

The horsepower or hp is the Imperial unit of measurement for power.

"Power" is the scientific term used to describe "capacity to perform some work".

These days, in most countries, it has been replaced by an SI unit, the watt (or, in practice, kilowatt).

The term brake horsepower refers to the rated output power of a machine, which is not to be confused with the amount of input power it requires to be able to generate that amount of rated output power.

In the case of a car engine, the brake horsepower (or kilowatts) is the power remaining after all the losses have been taken into account. (Heat emitted, gearbox friction, etc.) In other words, output power (brake power) is input power minus losses.

What is the equation of converting horsepower to joule?

Horsepower is a unit of power, but joules is a unit of energy. To convert horsepower to joules, you need an additional time parameter. One horsepower is about 745.7 watts. So a horsepower-hour is 745.7 watt-hours. One watt-hour is 3600 joules. A horsepower-hour is then 745.7 times 3600 = 2684520 joules.
