the cosmological constant is always dimensional less?

in the randall sundrum models the tension of our brane is

[tex]T=24M^3_5 \sqrt{\frac{-\Lambda}{24M^3_5}}[/tex]...the sub index of M is the number of dimension of space time and the supercript is the power.

¿whats units have the Planck scales [tex]M_4[/tex] and [tex]M_5[/tex]?...and then...¿whats units have the tension [tex]T[/tex]?

The cosmological has dimensions of mass squared in every dimension(units c= hbar=2)

where did you get this equation for T from?
