Moio (unit)

Moio, older spelling: Moyo, also as Mojo[1] was a unit of measurement that measured grain and liquid used in Portugal and its colonies and in Brazil. The moio has small measurement differences below the alqueire. In case of grain and salt, the moio was used.

The measurement was used until the time of the Portuguese Wars of Liberation in the 1830s when the country and the colonial empire adopted the metric system and in Brazil, when the country adopted the metric system. Not long after its adoption, along with other old units, traditional moios continued to be used.

  • 1 moio = 15 fangas/fanegas = 60 alqueires = 120 half alqueires (meios alqueires) = 240 quarts = 480 = eighths = 960 sixteenths (half eights) = 1,920 maquias.[2]
