Bully Metric

There are a surprising number of earth's physical constants that can be approximated using various algebraic combinations of the following four numbers:

10330
3055
2
0.40 

A few additional approximations (four digits) can be obtained from values used in the Bully Mnemonic. These include an approximate relationship of the speed of light to the Earth's radius (r ≈ 6371), Schwarzschild radius (R), standard gravitational parameter (μ = MG ≈ 3.984e14), and a typical gravitational acceleration on earth's surface (g ≈ 9.813 ).

$${\color {Red}1}0{\color {Red}33}0\times {\color {Red}3}0{\color {Red}55}=31558150={\frac {1\,Sidereal\,Year}{1\,Second}}$$

$$r_{earth}\approx {10^{-3}}\times c\times {\frac {{\color {Red}3}0{\color {Red}55}\,s}{\sqrt {{\color {Red}2}\times {{\color {Red}1}0{\color {Red}33}0}}}}=6371\,km$$

$$R_{earth}={\frac {2\times GM_{earth}}{c^{2}}}\approx {10^{-10}}\times c\times {\frac {{\color {Red}3}0{\color {Red}55}\,s}{{\color {Red}1}0{\color {Red}33}0}}\approx {8.866\,mm}$$

$${\mu }_{earth}=GM_{earth}\approx {10^{-10}}\times c^{3}\times {\frac {{\color {Red}3}0{\color {Red}55}\,s}{{\color {Red}2}\times {{\color {Red}1}0{\color {Red}33}0}}}\approx {398,400,000,000,000\,{\frac {m^{3}}{s^{2}}}}$$

$$g_{earth}={\frac {{\mu }_{earth}}{{r_{earth}}^{2}}}\approx {10^{-4}}\times c\times {\frac {1}{{\color {Red}3}0{\color {Red}55}\,s}}\approx {9.813\,{\frac {m}{s^{2}}}}$$
