    If you work in units where c = 1 and h-bar = 1, all physical quantities can be described as having a dimension (unit) which is some power of the mass.

    Mass, energy, and momentum have a dimension of mass (i.e. mass dimension = 1).
    Length and time have a dimension of 1/mass (i.e. mass dimension = -1).
    Angular momentum is dimensionless (i.e., mass dimension = 0).
