If Jupiter was condensed, how big would it be compared to Earth?

So from what I understand, Jupiter is entirely made of gas. I know that gases like helium have an expansion ratio, which is how much space it occupies when it evaporates.

Is it possible to get an average expansion ratio for Jupiter and therefore a measurement of how large Jupiter would be (in physical dimensions e.g. diameter) if we cooled it enough to condense?

The problem is that the compositions of the planets are very different. The best way to do this would be to compare the masses.

Earth = 5.972E24 kg

Jupiter = 1.898E27 kg

If Jupiter's density was made to be the same density as Earth, it would be 1.898E27/5.972E24 = 317 times the size of the Earth in terms of volume.
