abstract = "A basic quantity in the characterization of relativistic particles is the proton-to-electron (p/e) energy density ratio. We derive a simple approximate expression suitable to estimate this quantity, Up/Ue = (mp/me)(3−q)/2, valid when a nonthermal {\textquoteleft}gas{\textquoteright} of these particles is electrically neutral and the particles{\textquoteright} power-law spectral indices are equal – e.g., at injection. This relation partners the well-known p/e number density ratio at 1 GeV, Np/Ne = (mp/me)(q−1)/2.",
