Horsepower to BTU per Second Converter

Horsepower (hp) is a unit of power originally defined as the power needed to lift 550 pounds one foot in one second, approximately equal to 746 watts. It was created to compare the output of steam engines with the power of draft horses.

Horsepower was defined by James Watt around 1782 to market his steam engines by comparing their output to the familiar power of horses. It became the standard unit for mechanical power in English-speaking countries and remains widely used despite the adoption of SI units.

Horsepower is extensively used in automotive engines, mechanical equipment, and motor specifications. It's standard for car engine ratings, industrial machinery, pumps, and mechanical power transmission systems, particularly in the United States.

BTU per second (BTU/s) is a unit of power representing the rate of energy transfer of one British Thermal Unit per second. It's used in thermal engineering and HVAC applications, particularly in imperial unit systems.

BTU per second developed with the British Thermal Unit system and became important in thermal engineering and HVAC applications. It provided a power unit consistent with BTU energy measurements, particularly useful in heating and cooling system design.

BTU per second is used in HVAC engineering, thermal system design, and heating/cooling applications. It's standard in imperial unit thermal calculations, boiler specifications, and air conditioning system ratings.
