Horsepower (Metric)
The metric horsepower (hp) is a unit of power defined as exactly 735.5 watts, used to measure the power output of engines and motors.
History/Origin
The metric horsepower was introduced in the late 19th century as a standardized unit to quantify engine power, primarily in Europe, replacing traditional units like the imperial horsepower. It was adopted for consistency in engineering and automotive industries.
Current Use
Today, the metric horsepower is used mainly in automotive, engineering, and industrial contexts to specify engine power, especially in regions that utilize the metric system. It is also used in some countries for rating motor and engine capacities.
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.
