It is m3kg-1s-2
Cavendish measured the gravitational constant "G".
g, the force of the Earth's gravitational attraction, is not a constant.
Gravitational constant was determined by lord Henry cavendish in 1798 using a torsion balance .....G=6.67 *10^-9
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
Why g is called the universal gravitational constant.Answer:Because it's the constant in Newton's Law of Universal Gravitation.It's "gravitational" because it is related to gravity; "universal ... constant" because it is the same in all cases."Universal" because it applied to the whole of the Universe.Another answer. But, g isn't called the universal gravitational constant.g is the acceleration due to gravity on our planet only.= 9.81 m s-2The universal gravitational constant is G (often called big G ) = 6.673 x 1011 m3 kg-1 s-2.It appears in Newton's equation f= Gm1m2 / d2 .

There is no evidence to suggest that the gravitational constant 'G' is not the exact same number everywhere in the universe.
The g (pronounced /ˈdʒiː/) is a non-SI unit equal to the nominal acceleration of gravity on Earth at sea level (standard gravity), which is defined as 9.80665 m/s2 (32.174 ft/s2). The symbol g is properly written both lowercase and italic to distinguish it from the symbol G, the gravitational constant and g, the symbol for gram, a unit of mass, which is not italicized From Wikipedia
Among other things, it may refer to the gravitational constant - the constant of proportionality for the universal law of gravity. In SI units, it's magnitude is 6.67 x 10-11 m3kg-1s-2.
The forces are calculated from Newton's theory. F = G M1 M2 / R-squared. IN the formula M1 and M2 are the masses of the Sun and the planet and R is the distance. G is the gravitational constant, and in SI unit it is 6.670E-11 so that if the masses are in kilograms and the distance in metres, the answer is in Newtons.
Force gravitational = (mass of the object)(the gravitational constant) F=mg "g" is the gravitational constant, it is equal to 9.8 m/s^2

An upper case (capital) G.
The attraction between two objects is: G x m1 x m2 / distance squared where m1 and m2 are the two masses involved, and G is the gravitational constant - approximately 6.674 x 10 to the power -11, in SI units.
Formula for Gravitational potential is - G M / r Here G is universal Gravitation constant, M - mass of the planet and r is the distance of the point from the centre of the planet. The unit is J/kg If potential energy is needed then the potential is to be multiplied by the mass m. So gravitational potential energy = - G M m / r So the unit would be J (joule)
In 1789 Henry Cavendish measured G
