In SI the unit of force is newton (N); 1 N = 1 kg.m/s2.

The weight of an object is given as the formula W=mg where W is the weight, m is the mass and g is the gravitational acceleration (or the gravity of planet). On earth, g is generalized as 10 N kg-1(about 9.8 N kg-1 to be more exact). On the moon, it is about 10/6 N kg-1. So, the weight of a 10kg mass on earth would be 100 N (N is Newton, the SI unit for weight) while the mass would be 16.7 N on the moon.
n-1 = 1/n
