Moroccan units of measurement explained

A number of units of measurement were used in Morocco to measure length, mass, capacity, etc. Metric system has been compulsory in Morocco since 1923.^[1]

System before metric system

A number of local units were used.

Length

Several units were used. These units were variable, not rigidly defined.^[2] Some units included:

1 cubit = 0.533 m

1 canna = 0.533 m

1 pic = 0.61 m

1 tonni = pic.^{[1] [2]}

The code, covid, covado, cadee, or dhra was varied from 19.85 to 22.48 in (perhaps the best value was 20.92 in (0.531 3 m).^[3]

Mass

Several units were used. These units were variable, not rigidly defined.^[2] Some units included:

1 = 507.5 g

1 = 507.5 g

1 = 3 kg

1 = 22 rotal

1 = 100 rotal.^{[1] [2]} One rotl of commerce was equal to 1.19 lb while one rotl of the markets was equal to 1.7 lbs.^[3]

Capacity

Several units were used. These units were variable, not rigidly defined.^[2] Some units included:

1 = 56 L

1 = 56 L

1 mudd = 14 L

1 = 14 L.^{[1] [2]}
