F = Gm₁m₂/r²
consider two bodies of mass m1 and m2 separated by distance r then force is directly proportional to the product of massses and inversly proportional to the square of distance b/w them after removing the proportionality we get a contant universal gravitational constant
s.i. units we can rearrang the formula to
G = Fr²/ m₁m₂
si units of force = N (newton) , r= m (meters)
mass = kg (kilograms)
substituting in the above eqn we get
units of G = Nm²/kg² or Nm²kg⁻²
also dimensional formula = [M⁻¹L³T⁻²]
