In thermalConductivity, the dimensionless susceptibilities and the crossover functions of the critical enhancement were declared as thermal conductivities. In dynamicViscosity, the dilute gas viscosity is now a reduced quantity, with the conversions from "nm", "g/mol" and "uPa.s" made by reference values with units. In dtofphOnePhase, the slope of the supercritical initial temperature guess and the lower bound for the magnitude of the Newton determinant are constants with units.

Similar to #4834.

Values are unchanged up to rounding.
