Horsepower
Horsepower (hp) is a unit of power measurement originally developed to compare the power of engines and motors, representing the rate at which work is done or energy is transferred.
History/Origin
The term was introduced in the late 18th century by James Watt to compare the power of steam engines to draft horses. It became a standard unit in engineering and automotive industries, with its definition evolving over time from mechanical to metric standards.
Current Use
Horsepower is widely used today to rate the power output of engines, motors, and other machinery, especially in automotive, aerospace, and industrial applications. It remains a common unit for expressing engine power in many countries.
Kilojoule/second
A kilojoule per second (kJ/s) is a unit of power equivalent to one kilojoule of energy transferred or converted per second.
History/Origin
The kilojoule per second is derived from the SI units of energy (joule) and time (second), and has been used in scientific and engineering contexts to measure power, especially in fields like physics and energy studies.
Current Use
It is used to quantify power in various applications, including electrical power, mechanical power, and energy transfer rates, particularly where kilojoules and seconds are the relevant units.
