[No discussion of these polygonal weights. This is about the relationships between named units, not the physical artifacts. Most weights discussed theoretically are for dinars, that is, gold, not silver dirhams. The measures were different in different parts of the Islamic world. Maybe the locations and time-periods of these polygonal weights could be inferred if we knew the silver weight standards in various locations at various times.]
