I really enjoyed this and I plan to do some figuring on this to verify... I was struck by the idea that understanding the arc of movement in the heavens is one of the few natural round things I can think of. The arc can also only be proven through observation and measurement over great time. Finally I see the cubit as intersection human scale ergonomics with celestial movement. When I set up my shop a posted a scale based on Nippur Cubits. Which I have defined as 518.5 mm. I'm thinking I should make some adjustments. https://en.wikipedia.org/wiki/Ancient_Mesopotamian_units_of_measurement https://en.wikipedia.org/wiki/Ancient_Mesopotamian_units_of_... I got a lot out of this article but I'm cubit curious.

Length of Nippur cubit: 51.84 ± 0.02 cm Ratio to Egyptian cubit: 99/100 Divided into 28 fingers (each finger = 1.8514 cm) Relationship to Other Measurements One Roman foot = 24/25 of a Greek foot One Roman foot = 35/36 of an English foot One small egyptian cubit = 44.45cm = 6/7 of a Nippur cubit One Roman foot = 16 fingers = 1.852 x 16 = 29.63 cm One Nippur cubit = 28 fingers = 1.852 x 28 = 51.84 cm ±0.02 = 4/7 of one Roman foot Pyramid Measurements in Nippur Cubits Great Pyramid base: 440 Egyptian cubits = 444.4 Nippur cubits Great Pyramid height: 280 Egyptian cubits = 282.8 Nippur cubits Mathematical Connections Pyramid height (282.8 Nippur cubits): - √8 = 2.828 - 200*√2 = 282,8 (the height of the Great Pyramid) = 100*√8 Base diagonal: - 628.43 cubits = 200*π Finger measurement: - 1/100,000 of a mean meridian minute (99.95% precision) The silver number: 1 + √2 Some properties: 1.414 + 1 = 2.414 1 / 2.414 = 0.414 1.414 – 1 = 1 / 2.414 Using the Nippur cubit as measurement unit, the height of the Great Pyramid measures 200 × the silver ratio, and the diagonal of the pyramid's base measures 200 × π! The perimeter of the Great Pyramid measures half an arc minute of Earth's meridian with 99.98% accuracy, which is equivalent to the measurement made by Méchain and Delambre at the end of the 18th century, after 7 years of measurements and 9 years of calculations… Source: https://www.messagedelanuitdestemps.org/de-la-coudee-de-nippur-a-la-coudee-egyptienne/ https://www.messagedelanuitdestemps.org/de-la-coudee-de-nipp...
