Watt
The watt (W) is the SI unit of power, defined as one joule per second, representing the rate of energy transfer or conversion.
History/Origin
The watt was named after James Watt, the Scottish engineer and inventor, in 1889. It was adopted as the SI unit of power to standardize measurements in science and engineering.
Current Use
The watt is widely used today to quantify power in electrical devices, engines, and energy consumption, serving as a fundamental unit in physics, engineering, and everyday applications.
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.
