grav·i·ta·tion·al constant

(grăv′ĭ-tā′shə-nəl)
n. Abbr. G
The constant in Newton's law of gravitation that yields the attractive force between two bodies when multiplied by the product of the masses of the two bodies and divided by the square of the distance between them. Also called newtonian constant of gravitation.
