The almude or cântaro is an obsolete Portuguese unit of measurement of volume used in Portugal, Brazil and other parts of the Portuguese Empire. An almude was equivalent to 6 potes or 12 canadas. In Spain, the unit was called almud and it was much smaller.
The exact value of the almude was different from region to region. Some examples were:
- Portugal (modern standard): 16.7 liters
- Faro: 17.04 liters.
