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.
Exawatt
An exawatt (EW) is a unit of power equal to 10^18 watts.
History/Origin
The exawatt is part of the SI prefix system, introduced to represent extremely large power quantities, especially in theoretical physics and astrophysics, as the need to express vast energy outputs grew.
Current Use
Exawatts are primarily used in scientific contexts to describe the power output of large-scale phenomena such as stars and cosmic events; they are rarely used in everyday measurements.
