Abstract (English): The exponent of the inverse fine structure constant, exp α-1, used in conjunction with various combinations of the neutron, proton, and electron masses, permits the calculation of Planck mass as mPL = √ħc/G = 2.176 433 6(52) × 10-8 kg, where Newton's gravitational constant is G = 6.674 305(32) × 10-11 m³ kg-1 s-2, in excellent agreement with the 2024 experimental and statistical data which give G = 6.674 30(15) × 10-11 m³ kg-1 s-2.
