What Does FK Stand For?
FK stands for Femtokelvin
Femtokelvin (FK) is a unit of temperature measurement that represents one quadrillionth of a kelvin (10^-15 K). This extremely low temperature scale is used primarily in advanced physics research, particularly in the fields of quantum mechanics and condensed matter physics, where temperatures near absolute zero are critical for studying the properties of materials and the behavior of quantum systems. Femtokelvin-level temperatures enable scientists to explore phenomena such as superfluidity and Bose-Einstein condensation.
