it is the units necessary to cancel out the other parts of a force due to gravity question.
if you calculate force, Newtons aka kg m/s^2, then you multiply G by mass 1 x mass 2/ meters^2
the units are kg^2/m^2.
to get from kg^2/m^2 to N you have to multiply by m^3/(kg s^2), the units of the gravitational constant

m – Meter.
kg – Kilogram
s– Second.
m3 kg-1 s-2 is the unit of G in SI system
In a general system the unit is L^3 M ^ (-1) T^(-2).
L:length
M:mass
T: Time.
