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Today, the pferdestarke is largely obsolete and replaced by the SI unit watt, but it is still occasionally used in historical references and in certain European countries for measuring engine power.
Femtojoule/second
A femtojoule per second (fJ/s) is a unit of power representing the rate of energy transfer of one femtojoule (10^-15 joules) per second.
History/Origin
The femtojoule/second unit emerged with the development of high-precision measurements in nanotechnology and quantum physics, where extremely small energy transfer rates are relevant. It is derived from the SI units of energy (joule) and time (second), with 'femto' denoting 10^-15.
Current Use
The femtojoule/second is used in scientific research to quantify very small power levels, particularly in fields like nanotechnology, quantum computing, and molecular physics, where energy transfer rates are extremely low.
