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 (Electric)
Electric horsepower (hp) is a unit of power used to measure the rate at which electrical energy is converted into mechanical energy or work, equivalent to approximately 746 watts.
History/Origin
The electric horsepower was developed as an adaptation of the mechanical horsepower to quantify electrical power output, especially in electric motors and generators. It became a standard unit in electrical engineering to express the power of electric motors and appliances.
Current Use
Electric horsepower is used primarily in specifying the power of electric motors, generators, and other electrical devices, particularly in industries where electrical power measurement is essential for performance and efficiency assessments.
