Newton’s law of gravitation is expresssed in Eq. (1.1)
$$V = - {m_1}{m_2}G/r$$
where m1 and m2 are the masses of the two objects and G is Newton’s constant. This formula can be reexpressed in terms of the so-called Planck mass, mp:
$$V = hc/r({m_1}{m_p})({m_2}/{m_p})$$
where h is Planck’s constant divided by 2π. It is important to note that m is the inertial mass and not something specially introduced for gravity.
