Quote 'But first I have to define that value once again, as I have mentioned over the years in terms of an Old Meter unit of 39.375 or 39 3/8ths'
3937.5 miles = 6336.6187 modern metres 6336 is inches in mile coincidence?
To find that number exactly and approx;
The Babylonian value for pi 3.125 is one answer so treat it as the side of a cube and double the volume of the cube then find its side. 3.125 cubed = 30.51757812 x = 61.03515625 cube root = 3.937253281.
To find your number exactly use the approx. for the cube root of 2 ie 1.26 x 3.125 = 3.9375.
And to do this by construction divide 39375 into 63 even spaces and measure to the 50th = 3.125.
Note; in Indus valley feet 31.25 is length of Kings chamber 412.5 inches 34.375 imperial feet
