Solution

The gravitational force which is acting between two bodies of unit mass, and separated by a distance of 1 metre from each other is known as the gravitational constant.
The value of the Universal Gravitational Constant is $G = 6.67 \times 10^{- 11} N m^{2} / k g^{2}$
Hence, $N m^{2} / k g^{2}$ is the SI unit of $G$ i.e Gravitational Constant.
