1 derime = 1⁄120 rotto
1 wakea (ounce) = 1⁄12 rotto
1 mocha = 1⁄10 rotto
Two types of measuring system were used, one for dry measures and one for liquid measures.
Different units were used to measure dry capacities. One madega is approximately equal to 0.44 litres.
1 ardeb = 10 or 24 madega (these may sometimes be referred to as either the long ardeb, equal to 24 madega or the short ardeb, equal to 10 madega)
The kuba is approximately equal to 1.016 litres.
More than 70 different units are used in an ordinary household. Some of the more important units used are kilograms, kunna, medeb, esir, bobo, pieces, litres, tassa, kubaya, birchiko, sini, bottles, guchiye, sahen and weket.
