Nominal solar mass parameter ($(GM{)}_{\odot }^{\mathrm{N}}$)

The exact conversion factor $1.3271244\times 10^{20}{\mathrm{m}}^3{\mathrm{s}}^{-2}$. Dividing a measured gravitational parameter by this factor expresses a mass in nominal solar units, avoiding a separate conversion through the measured gravitational constant.^[ref]
