これは、重力効果の計算に関与する経験的比例定数であり、2つの体の間の重力$ f $を質量の積$ m_1 m_2 $と距離$ r $：$ f = g\ frac {m_1 m_2} {r^2} $。
SIユニットでは、その値は約6.674 \ Times 10^{-11} m^3 \ CDOT KG^{-1} \ CDOT S^{-2} $です。
It is an empirical proportionality constant involved in the calculation of gravitational effects, which connects the gravitational force $F$ between two bodies with the product of their masses $m_1 m_2$ and the inverse square of their distance $r$: $F = G\frac{m_1 m_2}{r^2}$.
In SI units, its value is approximately $6.674 \times 10^{-11} m^3 \cdot kg^{-1} \cdot s^{-2}$.
