The perimeter of the Great Pyramid is 2000 cubits or 1000 yards.
And we all eat with our ears, give or take an inch...
Mixing up measuring systems of at least 3 civilizations and a span of 5000 years is certainly not scientific.
The ancient Egyptian cubit changed several times over history and due to external influences, at Pharaohnic times the valid cubit was 7 4 finger palms or 28 digits. That comes to around 52 centimeters or 20.47 inches. Several measuring rods with that measure have been found from that time and no two are exactly alike diverging by several tenths of a centimeter... a good indication that precise reproducibility was an unknown art at the time. That alone drives the whole arc second theory at absurdum.
