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.

Cavendish measured the gravitational constant "G".

The gravitational constant is, well, constant. It's exactly the same on the moon as it is on the Earth, or on Mars, or at the center of the sun. The moon's gravitational pull is less because it has less mass, but the gravitational constant is the same.

g, the force of the Earth's gravitational attraction, is not a constant.

Gravitational acceleration is a constant value for a celestial body, and doesn't depend on air resistance/friction. The value on Earth is constant anywhere on Earth, just like the value on Mars is constant anywhere on Mars. In practical,however, this is different. Air resistance lowers the value of gravitational acceleration.

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.
