Invented and used in Damascus (Dimashq- modern-day Syria), it is an Islamic measure of weight (in Arabic script الرطل الدمشقي) equal to 600 dirhams (or 12 uqiyyah given that one uqiyyah weighs 50 dirhams).

The Damascus ratl (also, Dimashq’s ratl) is one of many versions of ratl, each of which was ascribed to a major city in the then Islamic state that spread over large swaths of land including the Levant, North Africa, Asia Minor, Central Asia, etc. The other versions of ratl include Baghdadian ratl, Alexandrian ratl, Hijazian ratl, etc.
