The picometre ( SI symbol: pm) is a unit of length in the metric system equal to 10⁻¹² metres.^[1]

To help compare different orders of magnitude this page lists lengths between 10⁻¹² m and 10⁻¹¹ m (1 pm and 10 pm).^[2]

1 pm = 1 picometre = 1,000 femtometres
1 pm = distance between atomic nuclei in a white dwarf
2.4 pm — The Compton wavelength of the electron.
5 pm — shorter X-ray wavelengths (approx.)
