To help compare different orders of magnitude this page lists lengths shorter than 10−12 metres (1 pm).
This series on orders of magnitude does not have a range of shorter distances
Contents
Shorter than 1 ym
- 1.62 × 10−35 metres = the Planck length (lengths smaller than this do not make any physical sense, according to current theories of physics)
1 ym to 1 zm
- 1 × 10−24 metres = 1 ym = 1 yoctometre, the smallest named subdivision of the metre in the SI base unit of length.
- 1 × 10−23 metres = 10 ym
- 2 × 10−23 metres = 20 ym, the effective cross-section radius of 1 MeV neutrinos as measured by Clyde Cowan and Frederick Reines[1]
- 1 × 10−22 metres = 100 ym
1 zm to 1 am
- 1 × 10−21 metres = 1 zm = 1 zeptometre = 1,000 yoctometres
- 2 × 10−21 metres = radius of effective cross section for a 20 GeV neutrino scattering off a nucleon[2]
- 7 × 10−21 metres = radius of effective cross section for a 250 GeV neutrino scattering off a nucleon[2]
- 1 × 10−20 metres = 10 zm
- 1 × 10−19 metres = 100 zm
- 310 zm — de Broglie wavelength of protons at the Large Hadron Collider (4 TeV as of 2012)
1 am to 1 fm
- 1 × 10−18 metres = 1 am = 1 attometre = 1,000 zeptometres
- 1 am — sensitivity of the LIGO detector for gravitational waves
- 1 × 10−17 metres = 10 am
- 1 × 10−16 metres = 100 am
- 0.85 fm — approximate proton radius[3]
1 fm to 1 pm
- 1 × 10−15 metres = 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[4]
- 2.81794 fm — classical electron radius[5]
- 7 fm - the radius of the effective scattering cross section for a gold nucleus scattering a 6 MeV alpha particle over 140 degrees[4]
- 1 × 10−14 metres = 10 fm
- 1 × 10−13 metres = 100 fm
- ≈ 1 × 10−13 metres = 1 x unit
- 1 × 10−12 metres = 1 pm = 1 picometre = 1,000 femtometres
