Two different sources of emergent gravity lead to the inverse square of length dimension of metric field, [gμν] = 1/[l]2, as distinct from the conventional dimensionless metric, [gμν] = 1, for c = 1. In both scenarios all the physical quantities, which obey diffeomorphism invariance, such as the Newton constant, the scalar curvature, the cosmological constant, particle masses, fermionic and scalar bosonic fields, etc., are dimensionless.
