If conformal Weyl scaling symmetry is postulated to be a general property of all elementary fields, both gravitational and electroweak theory are modified. In uniform, isotropic geometry, conformal gravitational and Higgs scalar fields imply a modified Friedmann cosmic evolution equation that defines a cosmological constant (dark energy). This equation has been parametrized to fit relevant cosmological data within empirical error limits. The Higgs mechanism for gauge boson mass is preserved in conformal theory, but the imaginary mass parameter $w^2$ of the Higgs model is required to be of dynamical origin. It is shown here in a simplified calculation that the cosmological time dependence of nominally constant parameters of a conformal Higgs model couples scalar and gauge fields and determines parameter $w^2$. The implied cosmological constant is in order-of-magnitude agreement with its empirical value.
