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.


Petajoule/second

A petajoule per second (PJ/s) is a unit of power representing the transfer or conversion of one petajoule of energy every second.

History/Origin

The petajoule (PJ) is a metric unit of energy introduced as part of the International System of Units (SI) to measure large quantities of energy. The concept of power in terms of energy per unit time has been fundamental in physics, with the watt (W) as the SI base unit. The petajoule per second emerged as a large-scale unit for high-energy power measurements, especially in fields like energy production and scientific research.

Current Use

Petajoule per second is used in scientific and engineering contexts to quantify extremely high power levels, such as in nuclear energy, large-scale power generation, and astrophysics. It is also used in theoretical and large-scale energy calculations where conventional units like watts are insufficient.
