There are several types of Horsepower. Hyundaipedia focuses on the car side of horsepower.
- Mechanical horsepower — 0.74569987158227022 kW (33,000 ft·lbf per minute)
- Base Horsepower
- The horsepower produced straight out of the engine.
- Wheel Horsepower
- The horsepower that is actually used at the wheels.
The most-common definition of horsepower for engines is the one originally proposed by James Watt in 1782. Under this system, one horsepower is defined as:
- 1 hp = 33,000 ft·lbf·min−1 = exactly 0.74569987158227022 kW
A common memory aid is based on the fact that Christopher Columbus first sailed to the Americas in 1492. The memory aid states that 1 hp = 1/2 Columbus or 746 W.
- In fourteen hundred and ninety-two
- Columbus sailed the ocean blue.
- Divide that son of a gun|son-of-a-gun by two
- And that's the number of watts in a horsepower too.
