Horsepower (550 Ft*lbf/s)
Horsepower (hp) is a unit of power measurement, defined as 550 foot-pounds of work per second (ft·lbf/s).
History/Origin
The horsepower was developed by James Watt in the late 18th century to compare the power of steam engines with draft horses, and it became a standard unit for measuring engine power.
Current Use
Horsepower is still widely used today to rate the power of engines and motors in automotive, aviation, and industrial applications.
Hectojoule/second
Hectojoule per second (hJ/s) is a unit of power representing one hundred joules of energy transferred or converted per second.
History/Origin
The unit hJ/s is derived from the SI unit joule (J) and the metric prefix hecto- (h), used to express larger quantities of energy transfer rate, particularly in scientific and engineering contexts. It has been used as an alternative to watts in certain fields, though watts are more standard.
Current Use
Hectojoule per second is occasionally used in scientific and engineering applications to quantify power, especially in contexts where larger energy transfer rates are involved. However, the watt (W) remains the standard SI unit for power, and hJ/s is less common in everyday use.
