How many times more pressure exists in the interior of jupiter compared to that of earth?

roughly 10 times

Explanation:

Unlike Earth, Jupiter is a gas giant. It is mainly composed of hydrogen (71%) and Helium(24%). As we go inside the Jupiter Temperature and pressure increases drastically high. Near the core the hydrogen in the Jupiter exists in metallic form. The interior of the Jupiter has an enormous pressure about 3000 GPa 4500 GPa. Whereas the Earth Interior pressure varies between 330 GPa to 360 GPa. So, roughly the pressure inside the Jupiter is 10 tomes than that of the Earth's inside.
