\nThe dimension of the gravitational constant ($G$) is M\u207b\u00b9L\u00b3T\u207b\u00b2.
\n<\/section>\n
\nThe gravitational constant $G$ appears in Newton’s Law of Universal Gravitation, which states that the force ($F$) between two masses ($m_1$, $m_2$) separated by a distance ($r$) is given by $F = G \\frac{m_1 m_2}{r^2}$.
\n<\/section>\n
\nWe can determine the dimensions of $G$ by rearranging the formula: $G = \\frac{F r^2}{m_1 m_2}$. The dimensions of Force ($F$) are [MLT\u207b\u00b2], distance ($r$) are [L], and mass ($m$) are [M]. Substituting these dimensions: $[G] = \\frac{[MLT\u207b\u00b2] [L]^2}{[M][M]} = \\frac{[ML\u00b3T\u207b\u00b2]}{[M\u00b2]} = [M^{1-2} L\u00b3 T\u207b\u00b2] = [M\u207b\u00b9L\u00b3T\u207b\u00b2]$.
