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.
Pound-Foot/minute
Pound-foot per minute (lbf·ft/min) is a unit of power representing the rate at which work is done or energy is transferred, specifically the amount of work in pound-feet performed per minute.
History/Origin
The pound-foot per minute has been used historically in engineering and mechanical contexts to measure power, especially in systems where imperial units are prevalent. It is derived from the foot-pound unit of work, divided by time in minutes, aligning with traditional British engineering practices.
Current Use
Today, pound-foot per minute is primarily used in specific engineering fields, such as mechanical and automotive industries, to measure torque-related power outputs, though it is less common than SI units like watts or horsepower.
