Planck's constant h and the gravitational constant G.

The article is devoted to the disclosure of the relationship between Planck's constant h and the gravitational constant G. Currently, Planck's constant h is determined with great accuracy. In contrast, the accuracy of measurements of the gravitational constant G is several orders of magnitude lower than the accuracy of other physical quantities, including Planck's constant h. The article reveals the relationship between the above constants and determines the exact value of the gravity constant G, obtained by calculation.
