Arroba

Unit of mass

Unit of mass

Arroba is a Portuguese, Catalan and Aragonese customary unit of weight, mass or volume. Its symbol is @.

History

The word arroba has its origin in Arabic ar-rubʿ (الربع) or "quarter," specifically the fourth part (of a quintal), which defined the average load which a donkey could carry.

Iberian Peninsula

In weight it was equal to 32 pounds (14.7 kg) in Portugal and 25 pounds (11.5 kg) in Galiza, Asturias, Euskal Herria, Aragón, Catalonia, València, Castille, León and Andalusia.

The unit is still used by cork merchants and pig farmers.

Latin America

The unit is still used in Brazil by the agricultural sector, mainly in the cotton and cattle business. The modern metric arroba used in these countries in everyday life is defined as 15 kg.

In Colombia, Ecuador, and Peru the arroba is equivalent to 12.5 kg.

In Bolivia nationally it is equivalent to 30.46 L. However locally there are many different values, ranging from 11.5 L in Inquisivi to 16 L in Baures.

Internet

In Luso-romance, Ibero-Romance and Occitano-Romance countries, "arroba" has continued as the word for the "@" symbol used in Internet email addresses and other messaging and collaboration software.
