Perhaps a better rounded approximation of the diameter of the Earth would be 6366 kilometres rather than your value of 6371 kilometres.
I base this on:
- a nominal Earth circumference of 40 000 kilometres
- a rounded approximation of pi (π) of 3.14159365359
When used to recalculate the Earth circumference these give a value of 39 998.770 kilometres.
