What happens to the potential energy of a body when its height is doubled?

We know the formula for the potential energy of a body, it is :

$P=mgh$

Here, $P\rightarrow$mass of the body

$g\rightarrow$gravitattional acceleration

$h\rightarrow$ height of the body

if we double the height of the body then its potential energy

$P'=mg(2h)$

Or $P=2mgh$

Or $P'=2P$

Therefore, the potential energy of the body gets doubled when its height is doubled.
