A mudu is a unit measure in Nigeria. It is typically an enamel bowl of 1.33 liters capacity. It is used to measure beans, garri, rice and similar foodstuffs. It is rarely used to measure liquids. The practice is to heap the stuff being measured until it forms a cone. This gives a mass between 1.13 and 1.5 kilograms depending on the substance. Things like garri and rice would weigh more since the individual grains are smaller.
This morning, I was wondering where the word comes from. It is a Hausa word which is derived from the Arabic mudd which means handful. This is unsurprising given the influence of Islam and Arabic on Hausa. Then I wondered if the mudd was descended from the modius. However, there does not seem to be a relationship.
By volume, the mudd is approximately 775 mililiters while the modius is about 8.73 liters.
