Variations & cautions

Dry capacity; later standard

References give different values for siegħ: one sixth or one tenth of a tomna. Both interpretations are shown separately; neither is a universal value.

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.
