Gravitational constant was determined by lord Henry cavendish in 1798 using a torsion balance .....G=6.67 *10^-9
6.67*10-11 Nm2 Kg-2
Cavendish measured the gravitational constant "G".
The gravitational constant was found by Newton, not Einstein.
The gravitational constant "G" is the same everywhere. The force of gravity on the moon, expressed as the acceleration of a falling body is 1.62 metres/sec2. compared with 9.81 m/s2 on the earth.
There is no evidence to suggest that the gravitational constant 'G' is not the exact same number everywhere in the universe.
Although Newton included the gravitational constant in his law of universal gravitational constant, its value was not determined until some 70 odd years after his death, when Henry Cavendish measured it in 1798.

There are several different universal constants: Avogadro's number, Gas constant, Gravitational constant. The question needs to be more specific.
The value of gravitational acceleration on Earth is approximately 9.81 m/s^2.
In physics, G usually refers to the gravitational constant, which is a fundamental constant that appears in the law of universal gravitation equation. The value of the gravitational constant is approximately 6.674 × 10^-11 m^3 kg^-1 s^-2.
