For the Portuguese unit, see fanga.

In Spain and the Spanish-speaking world, various units of dry capacity, mass and land area. Originally the fanega was a unit of dry capacity used for grain. It was also a unit of area, the amount of land that would be sown with a fanega of seed (see seed measures of land).

As a unit of capacity


In Spain, 20ᵗʰ century, a unit of dry capacity, about 55.501 liters (about 1.57 U.S. bushel).¹ link to a table showing relationships between Spanish units of dry capacity In earlier periods the value varied with locality, which is illustrated by the table below of values reported in the 19ᵗʰ century. Although the table gives values by province, bear in mind that in some provinces the same unit might be used throughout the province, but in others the value of the fanega would vary from village to village. The values reported by sources are typically those of the largest city.

A “media fanega” is half a fanega. Rather than multiplying everything by 2 to report values for the fanega, we have retained the term used in the source material, because the manner of reporting implies that the media fanega was the unit in everyday use.

As an example of the practical precison in grain measires of 1800.

La media fanega tendrá pues la forma que actualmente se la da; y consiste en un fondo de igual ancho, pero menos largo que la boca, sobre el qual se levantan tres lados planos y rectos, siendo el quarto lado inclinado para la comodidad de llenarla y vaciarla. La boca tendrá de largo 37 1/4 dedos; y de ancho 16½ dedos, incluyéndose en esto el grueso de los bordes. La luz de dicha boca, sin el grueso de los bordes, sérá de 35 dedos de largo y 15 dedos de ancho. El fondo tendrá de ancho 15 dedos y de largo 25½ dedos; la altura interior de la medida de 12 dedos.

Así en esta medida como en las demas de granos que se siguen no se exigirá que las dimensiones sean rigurosamente las que aquí se señalan, y se tendrán por buenas las medidas cuyas dimensiones no varien la quarta parte de un dedo en las de media fanega y quartilla y 1/16 de dedo en las demas; á excepcion de las dimensiones de las bocas, comprehendido el grueso de los bordes, en las quales no se permitirá mas diferencia que 1/8 de dedo en la media fanega y quartilla; 1/16 de dedo, en el celemín y medio celemín, y 1/32 de dedo en las restantes.

The media fanega will then have the form that is currently given; and consists of a bottom the width of the mouth, but not as long, on which three flat and straight sides rise, the fourth side being inclined for the convenience of filling and emptying it. The mouth will be 37¼ dedos long; and 16½ dedos wide, including in this the thickness of the edges. The opening of that mouth, without the thickness of the edges will be 35 dedos long and 15 dedos wide. The bottom will be 15 dedos wide and 25½ dedos long; the inside height of the measure is 12 dedos.

Thus, in this measure, as in the rest of the grain measures that follow, the dimensions will not be required to be rigorously those indicated here, and measures whose dimensions do not vary the fourth part of a dedo in those of media fanega and quartilla and 1/16 of dedo in the others; with the exception of the dimensions of the mouths, including the thickness of the edges, which shall not allow more difference than 1/8 of a dedo in the media fanega and quartilla; 1/16 of dedo, in the celemin and media celemin, and 1/32 of a dedo in the remaining ones.

As a unit of mass

The fanega seems to have became a unit of mass only in the New World. In the 19ᵗʰ century, it was a unit of mass in the cocoa trade, approximately 51 kilograms (except in Maracaibo, where it was approximately 44 kilograms). In Havana, it was both a measure of capacity (approximately 109 liters) and mass (approximately 92 kilograms). (Doursther 1840, page 145.)

Usase de la semilla agraria llamada caballería y da su subdivisión en fanegas: aquella de 1,104 varas de largo por 552 de ancho, cuya área ó superficie es la de 609,408 varas cuadradas, y ésta (la fanega) difiere en extensión de varios modos, según opiniones diversas de los labradores, quienes, si bien están de acuerdo con la medida cientifica tratándose de la caballeria, no lo están, sin embargo, respecto del número de fanegas que ésta deba tener, considerándola unos por cuatro fanegas, otros por cinco y algunos por seis, en lugar de las doce que le concede la medida agraria. De esas tres subdivisiones, parece que la tercera es la más adoptable, por tener alguna relación más apropiada con lo que la ciencia establece. Asi una fanega de sembradura está considerada prácticamente por el doble de la medida cientifica ó sea por una superficie de 101,568 varas cuadradas y sus lados de 368 X 276 varas.

Use of the agrarian seed called caballeria and give its subdivision into fanegas: that of 1,104 varas long by 552 wide, whose area or surface is 609,408 square varas, and this (the fanega) differs in size in several ways, according to diverse opinions of the farmers, who, although they agree with the scientific measure in the case of the caballeria, do not, however, [agree on] the number of fanegas that it should have, considering it one for four fanegas, others for five and some for six, instead of the twelve that the agrarian measure grants. Of these three subdivisions, it seems that the third is the most adoptable, because it has a more appropriate relationship with what science establishes. Thus a fanega de sembradura is considered practically as the double of the scientific measure or by an area of 101,568 square varas and sides of 368 × 276 varas.

La caballería de tierra se divide tambien en doce fanegas castellanas de sembradura de maíz, y la fanega tiene de área 50784 varas cuadradas, que resultan de multiplicar su largo 376 [sic, but a typographical error for 276. See note below] varas por su ancho 184 varas.

Se regulan caber en una caballería de tierra 69 fanegas de sembradura de trigo, ocupando cada fanega de éstas una estension superficial de 8832 varas cuadradas.

The caballería de tierra is also divided into twelve fanegas castellanas de sembradura de maiz, and the fanega has an area of 50784 square varas, which results from multiplying its length, 276* varas, by its width, 184 varas.

Sixty-nine fanegas de sembradura de trigo are arranged to fit in a cabellería de tierra, each fanega occupying an area of 8882 square varas.

The typo was finally spotted by José Paredes.



Son tan notables por su rara estravagancia, que con dificultad se concibe cómo puedan haber sido inventadas. Su falta de unidad se hará evidente, solo con recorrer las tablas adjuntas, aun sin hacerle caso á la bárbara nomenclatura de que se ha hecho uso. Entretanto, harémos notar que las superficies de los terrenos suelen á veces valuarse en caballerías, otras en fanegas de sembradura y otras en varas cuadradas, á lo que en realidad todas vienen á quedar reducidas, y es lo mas natural y sencillo.


They are so remarkable for their strange extravagance, that it is difficult to conceive how they could have been invented. Their lack of unity will be evident, just by going through the attached tables, even without paying attention to the barbarous nomenclature that has been used. In the meantime, we will note that the land areas are sometimes valued in caballerias, others in fanegas de sembradura and others in square varas, to which in reality all come to be reduced, and it is the most natural and simple thing.
