Neutrinos' maximum possible mass shrinks further (sciencenews.org)

TIL you can express mass in volts, and that electrons do not have a mass of 1 electron volt.

Because an eV is a unit of energy (1 eV = 1.602e-19 Joules). It's defined as the kinetic energy of an electron that is accelerated by a potential difference of 1 Volt, nothing to do with its rest mass.

When rest mass is stated in energy units such as eV, they're calculating it using E=mc^2.

Volts are energy per charge, right? So the cost of moving X charge from one place to another where the electric potential between them differs by voltage V, is X V?

Kind of like how lifting a mass involves increasing the g h , so costs energy m g h ?
