The same as the right hand side, [tex]\kappa T^{\mu\nu}[/tex]

It's a measurement of curvature, in [tex]m^{-2}[/tex].

I guess Mentz114 just wanted to motivate you to find it out yourself. It's not difficult.

I double-checked and found the units to be SI-consistent, as long as T is measured in J/m³.
