Gravitational potential energy can be given by the equation

PE = mgh

where m is the mass,

g is the gravitational constant 9.81 or 10 depending on rounding

and h is the height

well weight is a force equiavlent to

W = m*g

so comparing that to the potential energy equation, divide the potential energy by the height and you will get weight in Newtons
