Vacuum energy density versus geometric cosmological constant
= Vacuum energy density versus geometric cosmological constant
In $c=\hbar=1$ units, vacuum energy density has mass dimension four, Newton constant dimension minus two, and $\Lambda_{\rm geom}=8\pi G\rho_{\rm vac}$ dimension two. A value quoted in $\mathrm{GeV^4}$ is an energy density, not the geometric cosmological constant.
