Brazilian units of measurement
A number different units of measurement were used in Brazil to measure quantities including length, mass, area, and capacity, as those units were derived from Portugal and had significant local variances.
In 1814, as part of the Portuguese Empire, Brazil adopted the new Portuguese metric system, which was based in the original metric system, but with its units having Portuguese traditional names. This system was not, however, widely adopted and was soon abandoned, with the Portuguese customary units continuing to be used.
In 1862, the International Metric System finally became compulsory in Brazil.
A number of units were used with local variations.
1 palmo (palm) = 2/3 pés
1 vara (yard) = 3 1/3 pés
1 passo geométrico = 5 pés
1 braça (fathom) = 6 2/3 pés
1 légua (league) = 20000 pés.
1 onça = 1/16 libra
1 marco = 1/2 libra
1 arroba = 32 libras (One arroba métrica is equal to 15 kg.)(In Santos market Exchange, one arroba was 10 kg.)
1 quintal = 128 libras
1 tonelada = 1728 libra.
Different units were used to measure area in Brazil, often with significant local variations. One tarefa was equal to 3,000 to 4,000 square metres (0.30 to 0.40 ha). One alqueire was equal to 2.42×104 or 4.84×104 m2 (it was equal to 8 salamis and it was 33 l in Minas Gerais).
A number of different units with notable local variations were used in Brazil. One almude was equal to 31.944 l. One alqueire was equal to 40 to 320 l (generally for grain 33 l) (According to some sources, 1 alqueire = 5.324 l, alqueire (salt) = 4.076 l, 1 alqueire (common) = 3.626 l, 1 alqueire (Bahia) = 3.524 l, and 1 alqueire = 1/6 almude). Some of other units are provided below:
1 canada = 1/12 almude
1 moio = 10 almudes
1 pipa = 12 almudes
1 tonel = 30 almudes.
