BTU per Minute to Horsepower Converter

BTU per minute (BTU/min) is a unit of power representing the rate of energy transfer of one British Thermal Unit per minute. It provides an intermediate scale between BTU per second and BTU per hour for thermal power measurements.

BTU per minute developed as an intermediate unit for thermal power measurements, providing a convenient scale between the very large BTU per second and the smaller BTU per hour. It became useful for medium-scale thermal applications and equipment ratings.

BTU per minute is used in thermal equipment specifications, heating and cooling system ratings, and medium-scale thermal applications. It's found in thermal equipment ratings, industrial heating systems, and applications requiring intermediate thermal power scales.

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.
