Gravitational constant was determined by lord Henry cavendish in 1798 using a torsion balance .....G=6.67 *10^-9
The gravitational constant was found by Newton, not Einstein.
6.67*10-11 Nm2 Kg-2
Cavendish measured the gravitational constant "G".
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.
The exact value is not know but it is approx 6.67408*10^(-11) m^3kg^(-1)s^(-2)

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.

I think that g (the gravitational constant) varies dependent on your proximity to other massive bodies. For example the value of g on the moon is less than the value of g on earth. It is not constant throughout the universe.
The gravitational force between two objects depends on their distance, as well as the two masses involved. The value of the gravitational constant is 6.674 x 10^-11 (plus some units), in SI units. To get an actual force, multiply the two masses (in kilograms), divide by the square of the distance (in meters), and multiply that by the gravitational constant above. The answer is the force, in newton.
