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.
Millijoule/second
A millijoule per second (mJ/s) is a unit of power equivalent to one millijoule of energy transferred or converted every second.
History/Origin
The unit derives from the joule, the SI unit of energy, and the second, the SI unit of time. It has been used in contexts requiring small power measurements, especially in scientific and engineering applications, with the millijoule being a submultiple of the joule.
Current Use
Millijoule per second is used to measure small power levels in scientific experiments, electronics, and other fields where precise, small-scale power measurement is necessary, often within the context of energy transfer or consumption rates.
