Английская Википедия:Egyptian units of measurement
Шаблон:Short description A number of units of measurement were used in Egypt to measure length, mass, area, capacity, etc. In Egypt, the metric system was made optional in 1873 and has been compulsory in government use since 1891.[1][2]
Ancient Egyptian units of measurement
Units during the ending of the 19th century
A number of units were used in Egypt. Units and their interrelations were very variable in the national system.[1] Since 1891 their metric equivalences have been defined.[1]
Length
A number of units were used to measure length. One derah baladi was equal to 0.58 m and one kassabah was equal to 3.55 m, according to the metric equivalences defined in 1891.[1][2] Some other units according to the metric equivalences defined in 1891 are given below:[1][2][3]
1 kirat = Шаблон:Frac dirra
1 abdat = Шаблон:Frac dirra
1 kadam = Шаблон:Frac dirra
1 pic = 1 dirra
1 gasab = 4 dirra
1 mil hachmi = 1000 dirra
1 farsakh = 3000 dirra
There were six kinds of derah (a.k.a. dirra) as follows:[3] 1 Nile pic = 0.2545 m, 1 native pic (derah baladi) = 0.5682 m, 1 Constantinople pic (derah Istambuli) = 0.6691 m, 1 cloth pic (derah hendazeh) = 0.6479 m, 1 builder's pic (derah meimari) = 0.7500 m, 1 itinerary pic (aka. road-measure pic) = 0.7389 m.
Road Measures
One itenery derah was equal to 0.7389 m.[3] Some other units according to the metric equivalences defined in 1891 are given below:[1][2]
1 cassaba = 5 derah
1 bââh = Шаблон:Frac derah
1 mili = 500 cassabas = 1.148 mile (1.847 km)
1 farsakh (league) = 3 mili 1 Шаблон:Transl = 4 farsakh
1 safar yome (of which Шаблон:Frac make 1° of the meridian = 60 mili) = 2 Шаблон:Transl.
Mass
A number of units were used to measure mass. One oke was equal to 1.248 kg, according to the metric equivalences defined in 1891.[1][2] Some other units according to the metric equivalences defined in 1891 are given below:[1][2]
1 kirat = Шаблон:Frac oke
1 dirhem = Шаблон:Frac oke
1 Шаблон:Transl = Шаблон:Frac oke
1 Шаблон:Transl = 0.03 oke
1 rotoli = 0.36 oke
One harsela, used for weighing silk, is one oke.[3]
Area
A number of units were used to measure area. One feddan was equal to 4200.8 m2, according to the metric equivalences defined in 1891.[1][2] Some other units according to the metric equivalences defined in 1891 are given below:[1][2]
1 Шаблон:Transl = Шаблон:Frac feddan
1 Шаблон:Transl = Шаблон:Frac feddan[1][2][3]
1 Шаблон:Transl = 1 feddan.
Squares of derah and cassaba (3.55 m) was used to partly measure lands.[3]
Capacity
Two main systems, liquid and dry were used in Egypt.
Liquid Measure
One Шаблон:Transl was equal to 70.4467 quarts (Шаблон:Frac litres).[3]
Dry Measure
A number of units were used to measure capacity. One keddah was equal to 2.0625 L, according to the metric equivalences defined in 1891.[1][2] Some other units according to the metric equivalences defined in 1891 are given below:[1][2]
1 kirat = Шаблон:Frac keddah
1 khanoubah = Шаблон:Frac keddah
1 toumnah = Шаблон:Frac keddah
1 Шаблон:Transl = Шаблон:Frac keddah
1 nisf keddah = Шаблон:Frac keddah
1 malouah = 2 keddah
1 rob (roubouh) = 4 keddah
1 keila = 8 keddah
1 ardeb = 96 keddah
1 daribah = 768 keddah
Before 1891, according to the report of the United States Commissioners to the Paris Exposition of 1867, 1 ardeb was equal to 2.603 bushels (91.72 L).[3] Other authorities give the ardeb = 5.1648 bushels.[3] One ardeb of Alexandria was equal to 7.6907 bushels.[3]
