What are the appropriate units for the left half of the GR equation? Meters? square meters..? To put it another way, what exactly is being quantified?

The same as the right hand side, $$\kappa T^{\mu\nu}$$

It's a measurement of curvature, in $$m^{-2}$$.

Thanks, Ich. That's the answer I was looking for.

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

Note that Ich's answer assumes that geometric units are being used, which is very common, but perhaps not quite universal.

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