Pferdestarke
The pferdestarke (ps) is a unit of power used primarily in Germany, equivalent to 735.5 watts.
History/Origin
The pferdestarke was introduced in the late 19th century as a metric unit of horsepower, named after the German word for 'horsepower'. It was used to measure engine power, especially in automotive and engineering contexts.
Current Use
Today, the pferdestarke is largely obsolete and replaced by the SI unit watt, but it is still occasionally used in historical references and in certain European countries for measuring engine power.
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.
