Femtowatt
A femtowatt (fW) is a unit of power equal to 10^-15 watts, representing an extremely small amount of power.
History/Origin
The femtowatt was introduced as part of the SI prefixes to measure very small quantities of power, particularly in scientific and technological contexts, gaining recognition as the need to quantify minute power levels grew.
Current Use
Femtowatts are used in fields such as quantum physics, nanotechnology, and optical measurements, where precise measurement of extremely low power levels is required.
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Today, the pferdestarke is largely obsolete and replaced by the SI unit watt, but it is still occasionally used in historical references and in certain European countries for measuring engine power.
