hp·h to BTU

horsepower hour

• Definition: A horsepower hour is a unit of energy that measures the work done by a power of one horsepower over the duration of one hour.

• Symbol: The symbol for horsepower hour is “hp·h”.

• Usage: Horsepower hours are commonly used in mechanical engineering and automotive contexts to quantify the energy output of engines and machinery.

btu

• Definition: A British thermal unit (BTU) is a unit of energy defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

• Symbol: The symbol for BTU is “BTU”.

• Usage: BTUs are widely used in heating and cooling systems, as well as in the energy industry to measure the energy content of fuels.

Origin of the horsepower hour

• The concept of horsepower was developed in the late 18th century by James Watt to compare the output of steam engines with that of draft horses. The horsepower hour arose as a way to quantify energy over time, making it easier to assess the performance of engines.

Origin of the btu

• The British thermal unit was established in the 19th century, during the rise of the steam engine and the burgeoning fields of thermodynamics and heating sciences. It provided a practical measurement for energy transfer, particularly in heating and cooling applications.
