In 1795 Napoleon developed the metric system dividing the earth's circumference into 40,000,000 sections each section is known as a meter. Each quadrant arc of the earth is, therefore, 10,000,000 meters in length.
The earth's circumference is divided by a system which uses factors of 6 to the nth power as in our system of hours minutes and seconds which are divisable by 6.
In terms of distance also, the earth is divided by degrees minutes and seconds of arc producing the significant number "6 to the fourth power" or exactly
1,296,000. This number is related to the Egyptian RC.
The Greek stadia is known to be 600 Gk feet in length. An important question to solve, therefore, is how long was the Gk and Roman foot? Accurate calculations will lead to the relationship if any between the Greek foot and stadia length and a possible Egyptian geodetic connection. Greaves from Cambridge in 1639 and also Isaac Newton investigated possible metrical associations. Other scholars have also investigated see G.de Santillana and H.Von Dechend they wrote a very interesting work Hamlets Mill They and others explored these ancient measurements concluding that the length of a Roman foot was 11.664 inches and the Greek was 12.15 inches. This conclusion has been supported to a high degree of accuracy by scholars of Greek architecture. Measurement of the Parthenon both ancient and modern show it to have been constructed according to a principal of proportionate length and width. Penrose and others showed the length of the Greek foot to be exactly 12.15 inches, a significant Geodetic measure; and that the Parthenon proved its exact length. Given that the ancient Greeks used 600 Greek ft for their Stadia the true length of the Greek Stadia is seen, therefore, to be exactly 607.5 ft (modern) or 1/10 of a Nautical mile. In other words, the ancient Greeks knew a minute of arc at the Lattitude of Athens was equal to 10 Stadia and indeed, our Nautical mile is defined as exactly 6075 ft, as 1/21600 of the earth's circumference, that is, one minute of arc. This could of course be merely a coincidence. Is it also a coincidence that the the Egyptian measure of the Remen is found to be in proportion to the Greek Stadia? 500 Egyptian Remen equal exactly one Greek Stadia.
The length of the Greek foot correlates with a Geodetic origin when compared to the length of our Nautical mile. Dividing our Nautical mile we find one second of arc is 1/60 of a Nautical mile which calculates as 1215 inches. This proves the Greek foot to be represented mathematicaly as exactly 1/100 of a second of Arc of the earth's circumference at the lattitude of Athens. Athens is located at 37deg 58' North where the length of a degree is 110984.5 meters. The location of Athens and the calculation of the Greek foot in correspondance to that location provides a calculated length to the Greek foot using a geodetic formula and the Greek foot of 12.13 inches, within 2/100 of an inch of modern calculated values. Such accuracy provides mathematical support to the claim that a Geodetic correlation underlies the use and development of Greek and Roman feet and previously, Egyptian Cubits.
