Yeah, long and short billions might be an issue. Also, since we're looking at 4 significant figures, it's going to be written as either 4.792 billion or 4,792 million, so who cares?

More importantly, some stars may be less than a billion years old and even the oldest is going to be around 14-billion years old. [[https://en.wikipedia.org/wiki/Star#Age ref]] Since all of the stars should use the same scale and units, millions will be safer.
