    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
