`G = 6.67 xx 10^(-11) Nm^(2) (kg)^(-2) = ............(cm)^(3) g^(-2)g^(-1)`

Explanation

`G = 6.67 xx 10^(-11) Nm^(2) (kg)^(-2)`
`= 6.67 xx 10^(-11) (Nm^(2))/(kg^(2)) = 6.67 xx 10^(-11) kg xx (m)/(s^(2)) xx (m^(2))/(kg^(2))`
`= 6.67 xx 10^(-11) (m^(3))/(s^(2) xx kg)`
`= 6.67 xx 10^(-11) (xx (10^(2))^(3))/(10^(3)) ((cm)^(3))/(s^(2) xx g)`
`[because 1m = 100 cm = 10^(2)"cm तथा 1 kg" = 1000 g = 10^(3) g]`
`= 6.67 xx 10^(-11) xx (10^(6))/(10^(3)) (cm)^(3) s^(-2) g^(-1)`
`= 6.67 xx 10^(-8) (cm)^(3) s^(-2) g^(-1)`
