The enigmatic phenomenon of dark energy (DE) is the elusive entity driving the accelerated expansion of our Universe. A plausible candidate for DE is the non-zero Einstein Cosmological Constant manifested as a constant energy density of the vacuum, yet it seemingly defies gravitational effects. In this work, we interpret the non-zero Einstein Cosmological Constant through the lens of scale-invariant cosmology. We revisit the conformal scale factor and its defining equations within the Scale-Invariant Vacuum (SIV) paradigm. Furthermore, we address the profound problem of the missing mass across galactic and extragalactic scales by deriving an MOND-like relation within the SIV context. Remarkably, the values obtained for the Einstein Cosmological Constant and the MOND fundamental acceleration align with observed magnitudes. We also propose a novel early dark energy term within the SIV paradigm, which holds potential relevance for addressing the Hubble tension.
