1. All our weights & measures standards derive originally from the measure of length.
2. The (length) standard of the Great Pyramid is the old Egyptian royal cubit = 20.6357 inches. -Stecchini, pp. 311, 320 of Secrets of the Great Pyramid by P. Tompkins, 1971.
(1 inch = .0254 meters -British Imperial inch of 1824 and US inch of Congressional Act of 1928)
3. Newton used 20.63 old British inches = 1 royal cubit of Memphis, based upon Greaves’ Kings Chamber measurement–the room would thus be 20 X 10 royal cubits. (But the British changed their length unit, making it one-thousandth larger in 1824.)
4. Length of Egypt from Delta baseline at 31 degrees 6 minutes North to 24 degrees 0 minutes North is traditionally given as 1,500,000 royal cubits of .5241483 meters each.
-Stecchini, ibid., p. 321
5. 1000 royal cubits/second is Earth’s rotation speed, according to Tompkins and Stecchini, and that is why the ancient Egyptians enlightenly chose that unit of measure.
The reason I cite these 5 key facts is that a very great amount of confusion has for very long surrounded the issue of the standards of measures and weights–what they clearly are and where they came from originally. -Roger
