The magical mystical cubit

I’m leaving out 1/√(364.75/100) until such time as I have a better explanation for it. (Although it does effectively pop up in the discussion about the nautical mile.)

According to Wikipedia, the Reed was different things at different times … at one point being only 2 cubits, about 1 metre, long. They also called the 6-royal-cubit length “kalamos”. Given that we’re dealing with civilizations that lasted thousands of years, it’s hard to know what’s what.

I suspect that’s why there are different versions of the Royal cubit floating around … on the one hand, copy errors, on the other people using actual body parts to create measurements. It is my humble opinion that whoever came up with these things did it very logically, based on maths, and the metre and pi and phi. The big remaining question is how the heck did they get the metre.
