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.
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.
