Sure! Horsepower (British), often referred to simply as "horsepower," is a unit of measurement for power. Specifically, one horsepower (British) is defined as 550 foot-pounds per second or approximately 745.7 watts.
Horsepower (metric), sometimes referred to as "Pferdestärke" (PS), is slightly different. One metric horsepower is defined as 735.5 watts.
To convert from British horsepower to metric horsepower, you can use the following relationship: 1 Horsepower (British) ≈ 745.7 W 1 Horsepower (metric) ≈ 735.5 W
So, to convert from British horsepower to metric horsepower:
Thus,
| British HP (HP) | Metric HP (PS) | Example Application |
|---|---|---|
| 1 | 1.014 | Small electric motor |
| 10 | 10.14 | Riding lawn mower |
| 100 | 101.4 | Compact car |
| 300 | 304.2 | Sports car |
| 500 | 507 | High-performance sedan |
| 700 | 709.8 | Supercar |
These examples illustrate the slight difference between British and metric horsepower due to their different definitions in terms of watts. This small difference can still be significant when comparing the output of engines and machinery.

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.
You're referring to the metric unit of measurement for power!
In the metric system, a unit called "horsepower" or "HP" (short for "Pferdestärke", German for "horse strength") is used to express power. However, it's not directly equivalent to the imperial unit of horsepower.
1 metric horsepower (or PS) is defined as 735.5 watts or 0.9869 imperial horsepower. This means that if you see a rating in metric horsepower, you can convert it to watts by multiplying by 735.5.
In everyday applications, especially in European countries, motor power is often measured and specified in kilowatts (kW) or metric horsepower (PS).
