The weight on earth is $= 637 N$ $=637N$

The mass is the same everywhere.

$m = 65 k g$ $m=65kg$

The weight is a force and it is

$w = m g$ $w=mg$

Where the acceleration due to gravity is $= g$ $=g$

On Earth it is $g = 9.8 m s^{- 2}$ $g=9.8ms^-2$

The weight on earth is

$w_{e} = 65 \cdot 9.8 = 637 N$ $w_e=65*9.8=637N$
