Horsepower (British) and British thermal units per second (BTU/s) are both units of power. Horsepower is often used in the context of engines and machinery, while BTU/s is frequently used in heating, ventilation, and air conditioning (HVAC) systems.
Here's how you can convert horsepower (British) to BTU/s:
1 British horsepower (hp) is defined as 550 foot-pounds per second (ft·lb/s).
1 BTU is equal to approximately 778.169 foot-pounds (ft·lb).
Now, to convert 1 horsepower (British) to BTU/s, you can follow these steps:
Start with the definition of British horsepower: 1 hp = 550 ft·lb/s
Since 1 BTU is approximately 778.169 ft·lb, we need to convert foot-pounds per second to BTUs per second:
\text{1 hp} = 550 \, \text{ft·lb/s} \cdot \left(\frac{1 \, \text{BTU}}{778.169 \, \text{ft·lb}}\right)
Performing the calculation:
So, 1 British horsepower is approximately equal to 0.7068 BTU/s.
Car Engines: A typical family car might have an engine rated at around 150 hp.
Lawn Mowers: A standard lawn mower might have around 4 hp.
Heavy Equipment (e.g., Bulldozers): A large bulldozer might have a power rating of 300 hp.
Air Conditioning Units: A powerful central air conditioning unit for a large home might require around 5 hp.
Marine Engines: A yacht’s engine could easily be rated at around 1000 hp.
By converting horsepower to BTU/s, you can better understand the power output in terms that might be more familiar or relevant to certain applications, particularly in fields like HVAC where BTUs are commonly used.

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.
British Thermal Units (BTUs) are a unit of energy, and when measured over time, they can be expressed in various ways to indicate different rates of energy transfer. British thermal units per second (or BTU/s, also denoted as Btu/s) is a measure of the rate at which heat or energy is being transferred.
It's essentially an expression of how quickly one BTU unit of energy is being used up or transferred over a one-second period. This unit is commonly used in discussions about power and rates of energy consumption or production, particularly when dealing with processes that involve significant amounts of energy, such as industrial operations, heating systems, and even some types of engines.
To put this into perspective, consider that 1 watt (a standard unit of electrical power) is equivalent to 3.412 BTU/s. Thus, a device or process consuming 100 watts would be using approximately 341.2 BTUs per second.
