What Does FM Stand For?
FM stands for Femtometre
FM, or femtometre, is a unit of length in the metric system equal to one quadrillionth (10^-15) of a meter. It is primarily used in the field of nuclear physics to measure subatomic distances and the size of atomic nuclei, reflecting the extremely small scales at which fundamental particles and interactions occur.
