The practical unit of power in engineering is __________.

An engine's power is measured in horses in the imperial system. As the amount of work completed in a given amount of time. James Watt is credited with coining the phrase "horsepower." It is a unit of power that contrasts a machine's power with a horse's physical power. In the past, it was used to compare the output of steam engines to that of draught horses. Later, it was extended to include many kinds of turbines, electric motors, and piston engines.

33,000 pounds per minute are equivalent to one horsepower.

Horse power (hp) is the practical unit of power. 
1 hp = 746 W,
where W is Watt (the SI unit of power).
