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.


Femtowatt

A femtowatt (fW) is a unit of power equal to 10^-15 watts, representing an extremely small amount of power.

History/Origin

The femtowatt was introduced as part of the SI prefixes to measure very small quantities of power, particularly in scientific and technological contexts, gaining recognition as the need to quantify minute power levels grew.

Current Use

Femtowatts are used in fields such as quantum physics, nanotechnology, and optical measurements, where precise measurement of extremely low power levels is required.
