1/(((137036^4) / (pi / 2))^0.5 = 6.6740674559418824387e-11

Fine-structure constant

(((137036^4) / (pi / 2))^0.5) * G = 1.00000188

((4pi) / (1e+11^(4/3)))^(3/4) = 6.6743257e-11

G * (0.1 / (((4pi) / 1e+16)^(3/4))) = 0.999963183

((1 / 6.6743257e-11)^(3/4)) * 7 = 299772985.424

1 / ((2.99792458e+8^(4/3)) / (7^(4/3))) = 6.6737477e-11

6.6737477e-11 / G = 0.99995021
