Answer:
I assume this question is about gravitational constant G used in Gravitational field.
 
The gravitational force of attraction between two masses m1 and m2 which are kept at distance d from each other is given by
 
begin mathsize 12px style F space equals space G fraction numerator m subscript 1 m subscript 2 over denominator d squared end fraction space.............. left parenthesis 1 right parenthesis end style
where G is universal gravitational constant and its value is given by, G = 6.67408×10-11 m3 kg-1s2
when m1 , m2 are unit mass and distance d is unit distance, then we have F = G
 
Hence gravitational constant G is the gravitational force of attraction between unit masses which are kept at a unit distance from each other
