- E = hf - W, where E is energy in eV, h = 4.14 x 10
^{-15}eV-s, f is frequency in Hz, and W = 2.27 eV.

- E = (0.885 MeV-km)/R, where E is energy in MeV and R is radius in km.

- R = (0.0012 pm - (amu)
^{-1/3}) M^{1/3}, where R is radius in pm (1 pm = 10^{-12}m) and M is mass in atomic mass units (amu; 1 amu = 1.67 x 10^{-27}kg).

- t
_{L}= 26 ns.
