To help compare different orders of magnitude this page lists lengths between 10−15 metres and 10−14 metres (1 Femtometre (fm) and 10 fm).
- 1 fm = 1 femtometre = 1,000 attometres
- 1.5 fm — diameter of the Scattering Cross Section of an 11 MeV proton with a target proton[1]
- 2.81794 fm — classical electron radius[2]
- 7 fm - the radius of the effective scattering cross section for a gold nucleus scattering a 6 MeV alpha particle over 140 degrees[1]
