Femtometer (fm) is a unit in the category of Length. It is also known as femtometers, femtometre, femtometres. This unit is commonly used in the SI unit system. Femtometer (fm) has a dimension of L where L is length. It can be converted to the corresponding standard SI unit m by multiplying its value by a factor of 1E-015.

Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).
