Libyan units of measurement
A number of different units of measurement were used in Libya to measure length, mass, area, etc. Metric system adopted in Libya in 1927.^{[1]}

System before the metric system
A number of different units were used.
Tripoli and Cyrenaica
Length
Several units were used to measure length. One pik was equal to 0.68 m as it was defined by metric equivalent.^{[2]}^{[3]} Some other units are given below (Note: these units too were defined by metric equivalents):
1 handaze = 1 pik
1 palmo = 1/3 pik
1 draa = 0.46 m.^{[2]}^{[3]} In tripoli, draa was equal to 26.42 in and arbi draa (lesser pik) was equal to 19.029 in.^{[4]}
Mass
A number of units were used to measure mass. One rottolo was equal to 0.512 8 kg as it was defined by metric equivalent.^{[2]}^{[3]} Some other units are given below (Note: these units too were defined by metric equivalents):
1 oka = 2.5 rottolo = 1282 g
1 metical = 4.76 g
1 kharouba = 1/2560 oka
1 dram = 1/160 oka
1 termino = 1/128 oka
1 uckin = 1/16 oka
1 mattaro = 42 oka
1 cantar = 100 oka.^{[2]}^{[3]} In Tripoli, metical (73.6 grains) wnuas to measure gold and silver.^{[4]}
Area
Several units were used to measure area. One pik^{2} was equal to 0.4624 m^{2} as it was defined by it metric equivalent.^{[2]}^{[3]} Some other units were given below:
1 denum = 1600 pik^{2}
1 jabia = 1800 pik^{2}.^{[2]}^{[3]}
Capacity
Two systems, dry and liquid were used to measure capacity.
Dry
Several units were used to measure dry capacity. One orba was equal to 7.5 l as it was defined by metric equivalent (According to some sources, one orba was equal to 7.692 l^{[3]}).^{[2]} Some other units were given below:
1 nufsorbah = 1/2 orba
1 marta = 2 orba^{[3]}
1 kele = 2 orba^{[3]}
1 temen = 4 orba
1 ueba = 16 orba.^{[2]}^{[3]}
Following units were also used to measure dry capacity by weight:
1 oka =1282 g (defined by metric equivalent)
1 marta = 11 - 14 (oka of water)
1 kele = 2 marta.^{[2]}^{[3]} In Tripoli, 1 cafiso (20 tiberi) was equal to 1.152 bushels.^{[4]}
Liquid
Several units were used to measure liquid capacity. One barile was equal to 64.8 l as it was defined by metric equivalent (According to sources, one barile was equal to 62.4975 l.^{[3]}).^{[2]} One bozze was equal to 1/24 barile.^{[2]}^{[3]} One gorraf was equal to 1/5 barrile, and giarra was nearly equal to 50/71 barile.^{[3]} Following units were also used to measure liquid capacity by weight:
1 oka = 1282 g (defined by metric equivalent)
1 gorraf = 9.75 oka (of water)
1 giarra = 58.5 oka.^{[2]}^{[3]} In Tripoli, Mataro, for oil, was equal to 9.163 gal.^{[4]}
Marj (ancient Barca) and Fezzan
Barca and Fezzan had the same units as units in Tripoli.^{[4]}
