Abstract
We have analyzed the retrieval of the relation between mass and absolute Gaia G magnitude as obtained from theoretical models by \cite{2012MNRAS.427..127B} for the stars of different luminosity classes. For subgiant and main-sequence stars, we provide approximate analytical direct and inverse relations based on the most probable value of G magnitude in the course of evolution within the given stage. A comparison with (albeit few) observational data confirms that our results can be used for the estimation of the stellar mass from Gaia photometry in the range of 1 to 10 solar mass. We argue that similar relations for other luminosity classes are not informative.
