Horsepower (British) is a unit of power commonly used to quantify the rate at which work is done. The British system defines 1 horsepower (HP) as the power required to do 550 foot-pounds of work per second. Therefore, the conversion from horsepower to foot-pounds per second is straightforward:
Automobiles:
Motorcycles:
Lawn Mowers:
Air Conditioning Systems:
Industrial Equipment:
Remember, the conversion factor between horsepower and foot-pounds per second can be used reciprocally. If you know a machine's power output in foot-pounds per second, you divide by 550 to get the power in horsepower.
For example:
Understanding these conversions can help you better grasp the scale of power that different machines and engines can produce.
See below section for step by step unit conversion with formulas and explanations. Please refer to the table below for a list of all the Foot-pounds per second to other unit conversions.
A classic British unit of measurement!
In the United Kingdom, "horsepower" or simply "hp" has a slightly different meaning than in the United States.
In the UK, one horsepower (hp) is defined as 550 foot-pounds per minute. This is equivalent to about 745.7 watts, which is roughly 0.746 kilowatts.
To put it into perspective, one horsepower is roughly the power output of a small to medium-sized pony or a horse working at a moderate pace. In other words, it's the power required to do work that would normally be done by a strong animal.
In contrast, in the United States, one horsepower is defined as 33,000 foot-pounds per minute, which is equivalent to about 745.7 watts as well, but with a different unit of measurement (foot-pounds). This means that US and UK "horsepower" are effectively identical, despite their slightly different definitions.
In everyday life in the UK, horsepower is often used to describe the power output of engines, machinery, and other devices, particularly in the context of transportation, engineering, and industry.
Foot-pounds per second (ft-lbf/s) is a unit of measurement that represents the rate at which work is being done, typically in applications involving mechanical power or energy transfer.
In essence, it's a measure of how fast an object can apply force to a surface over time. To break it down:
So, if something is doing 100 ft-lbf/s of work, it means that it's capable of delivering 100 foot-pounds of work in just one second. This can be useful for measuring the power output of engines, motors, or other machines that convert energy into motion or mechanical work.
