Algerian units of measurement

A number of different units was used in Algeria. A number of different units were used to measure length, mass and capacity. From 1843, Algeria was adopted to use France system of units (i.e. Metric System).^[1]^[2]

Pre-metric Units

Before 1843, a number of different units was used to measure length, mass and capacity.^[1]^[3]

Units of Length

Different units were to measure length. One pic (dzera à torky) was equal to 0.640 m^[1] (or 0.623 m ^[3]) while pic (dzera à rabry) was equal to 0.480 m^[1] (or 0.467 m^[3]). Some other units are given below:^[1]^[3] 1 termin = 1/8 pic

1 rebia = 1/4 pic

1 nus = 1/2 pic.

Units of mass

A number of different units was used to measure mass. One ukkia (ounce) was equal to 0.03413 kg. One metical (metsquat) was equal to 0.0047 kg as an approximate value.Some other units are given below:^[1]^[4]

1 rottolo à thary = 16 ukkia

1 rottolo à khadhary = 18 ukkia

1 rottolo à kebyr = 24 ukkia

1 cantar = 100 rottolo (cantar(kebyr) = 100 rottolo à thary, cantar(khaldary) = 100 rottolo à khadhary, and cantar (thary) = 100 rottolo à thary^[4]).

In addition to above units, one gyral was equal to 207 mg.^[4]

Capacity

Two different systems were used to measure capacity: one for dry remeasure and another for liquid measure.^[1]

Dry

Some units used to measure dry capacities are given below:^[1]

1 caffiso (or calisse^[3]) = 317.47 l (Note: in an old publication, one caffiso was equalised to 8 saah even though the given values are mismatched with that^[5])

1 saah (or ssah^[3]) = 58 l

1 tarri(or tarie^[3]) = 1/12 caffiso.

Liquid

One khoull (or Khoul or kolleh^[3]) was equal to 16 2/3 l or 16 l.^[1] On Metalli (oil) was equal to 17.90 l.^[3]
