    It's the gravitational pull due to a planet on earth it is around 10

    *change in height x density x acceleration due to gravity

    Is this the same equation as the one for pressure? Cause I know its pressure=force/area but is it also pressure=g x h x density?

      i don't think so because this is about the difference in pressure, not the pressure itself
