Editing Dirham (section)

==Unit of mass==
The dirham was a unit of mass used across North Africa, the Middle East, Persia and [[Ifat Sultanate|Ifat]]; later known as [[Adal Sultanate|Adal]], with varying values.

The value of Islamic dirham was 14 qirat. 10 dirham equals 7 [[mithqal]] (2.975 gm of silver).

In the late Ottoman Empire ({{langx|ota|درهم}}), the standard dirham was 3.207 [[gram|g]];<ref>based on an oka of 1.2828 [[kilogram|kg]]; Diran Kélékian gives 3.21 g (''Dictionnaire Turc-Français'', Constantinople: Imprimerie Mihran, 1911); Γ. Μπαμπινιώτης gives 3.203 g (''Λεξικό της Νέας Ελληνικής Γλώσσας'', Athens, 1998)</ref> 400 dirhem equal one [[oka (measure)|oka]]. The Ottoman dirham was based on the [[Sassanian|Sasanian]] drachm (in [[Middle Persian]]: 𐭦𐭥𐭦𐭭 ''drahm''), which was itself based on the Greek [[Ancient drachma|dram/drachma]].<ref>{{Cite web |title=DIRHAM - Encyclopaedia Iranica |url=https://iranicaonline.org/articles/dirham}}</ref>

In [[Egypt]] in 1895, it was equivalent to 47.661 [[troy grain]]s (3.088 [[gram|g]]).<ref>[[OED]]</ref>

There is currently a movement within the Islamic world to revive the dirham as a unit of mass for measuring silver, although the exact value is disputed (either 3 or 2.975 grams).<ref>{{Cite journal|last=Ashtor|first=E.|date=October 1982|title=Levantine weights and standard parcels: a contribution to the metrology of the later Middle Ages|url=https://www.cambridge.org/core/product/identifier/S0041977X00041525/type/journal_article|journal=Bulletin of the School of Oriental and African Studies|volume=45|issue=3|pages=471–488|doi=10.1017/S0041977X00041525|s2cid=140561646|issn=0041-977X|access-date=2019-11-20|archive-date=2024-01-02|archive-url=https://web.archive.org/web/20240102084427/https://www.cambridge.org/core/journals/bulletin-of-the-school-of-oriental-and-african-studies/article/abs/levantine-weights-and-standard-parcels-a-contribution-to-the-metrology-of-the-later-middle-ages/A083FE1D62824E92B13D5A0D61336490|url-status=live|url-access=subscription}}</ref>
