Unit Description
BTU per Hour (BTU/hr)
Definition
BTU per hour (BTU/h) is a unit of power representing the rate of energy transfer of one British Thermal Unit per hour. It's widely used in HVAC applications and provides a practical scale for heating and cooling system ratings.
History
BTU per hour became the standard power unit for HVAC systems and thermal equipment. It provided an appropriate scale for heating and cooling applications, becoming universally adopted in the HVAC industry and building energy systems.
Current Use
BTU per hour is extensively used in HVAC systems, heating and cooling equipment ratings, building energy calculations, and thermal system specifications. It's standard for furnace ratings, air conditioner capacity, and building thermal load calculations.
Horsepower (hp)
Definition
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.
History
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.
Current Use
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.
