Also this literally doesn't work. Like: If the person's 6 ft tall, then the square root of the height is 2.44 and their new height is 14.6 ft
but if the person is 2 meters tall, then the square root of the height is 1.41 and their new height is 2.82 meters = 9.25 feet
and it would make basically no sense to fix the units as anything (except for the planck length, but then they'd be larger than the earth).
