How does one figure out the units of measure for the cosmological constant? In the Einstein Field Equation:
[tex]\[Rab - \frac{1}{2}Rgab + \Lambda gab = 8\pi Tab\][/tex]
Lambda is a constant but the units of measure for gab and Tab differ for each combination of indices. For example T00 is an energy density. So what is the measure for g00 so that Lambda comes out to a measure of one over meters squared?
Thanks.
