# Do neutrinos have mass? [closed]

I'm really curious on this subject and I want to know if neutrinos have mass. I know they are a subatomic particle, but how much mass.

Neutrinos indeed do have mass, we don't know how much mass exactly, but ongoing research have put upper limits of about 0.3 eV [Thanks to Giorgio Comitini for providing a more accurate value]. Compare with e.g. an electron which has a mass of about $0.5 \times 10^{6} eV$.
