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

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
  • 1 × 10−22 metres = 100 ym

1 zm to 1 am

  • 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

1 am to 1 fm

  • 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 × 10−14 metres = 10 fm
  • 1 × 10−13 metres = 100 fm

Distances longer than 1 pm
