Variations & cautions

Later standard; not universal

Construction and old plans require attention to the standard. Bianco discusses a 2.088 m factor; later tables are represented here by a qasba of about 2.096 m.

A calculation can be mathematically precise while its historical equivalence remains approximate. Each variant here carries its context and sources. Displaying more decimal places does not make a rounded value more certain.
