If there is a formula giving one quantity as a constant times another quantity,
sometimes measurements of the one quantity are expressed in units of the other
quantity for computational and notational convenience.  Since the mass of
something and its energy are related, in relativistic physics, by a constant
whose value is the square of the speed of something massless (like light),
if one is working in relativistic physics one can measure mass in units of
energy or vice versa.
