What is the meaning of m3 kg-1 s-2 in gravitational constant

Click For Summary
SUMMARY

The discussion clarifies that the units of the gravitational constant (G) are expressed as m3 kg-1 s-2. This unit representation is derived from the relationship between force, which is measured in kg m s-2, and the formulation of Newton's law of gravitation. Additionally, G can also be represented as N m2 kg-2, reinforcing its significance in gravitational calculations.

Force has units kg\ m\ s^{-2}, the units in the gravitational constant just make this come out.
 
Note that you can also write the units of G as N\;m^2\;kg^-2. This makes its role in Newton's law of gravitation even more obvious.
