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.
Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
