As a generalization, ’Earth commensurate measure’ is understood to have its origins from land surveying developments in ancient Mesopotamia and Egypt, later adopted by the Hellenistic Greeks and subsequently by the Romans and the English. Most recently, the French implemented the ‘metric’ model via Gabriel Mouton.
In this current era, Earth commensurate measure is found in the relationship of the English Mile relative to the Metric Kilometer through the ratio of 1:1.60934; approximately 1:φ.
This primal correlation is more historically preserved in the Roman Passus relative to the English Yard through the ratio of 1:1.6204724409449; approximately 1:φ.
The Roman common Passus (double step/stride) is defined as two Roman common Gradi, or five Roman Feet.
