Equation [2].

PNG image of [2] in main body text.

Using m,s, kg units, all of the terms in the equation, except one, have dimensions m^2/s^2. In order for the term with the Cosmological Constant,Lambda, to also have these units, Lambda must have units 1/m^2. This seems to me to be an oddity.

I am hoping someone can explain to me why the

__constant__Λ has units 1/m

^{2}.

In the article

In the

__Equations__section, the following equation is presented.

Do tensors have dimensions? If so, can someone tell me what the dimensions are for these three tensors: R, g, and T? I know the dimensions for G and c. I am guessing the constant R has the dimension 1/m

^{2}since apparently Λ also does.
