In Spain, ? – 1731, a unit of mass used only for gold, = ¹⁄₅₀ of a marco of Castile, about 4.9 grams. link to a table showing relationships between Spanish units of mass used for precious metal Its use in Spain was ended by a royal order of 31 August 1731, but it continued in use in South America. It was also used to indicate the gold content of alloys.

El Castellano, que sirve á ensayar al oro, tiene 24 quilates, el quilate tiene 4 grános, y el grano 8 partes.

El Marco, para el ensayo de la plata, se divide en 12 dineros, y cada dinero en 24 granos.

La ley de la plata labrada debe ser de 9 dineros. Los Contrastes se sirven de diferentes marcas para sellarla.

El Marco Castellano, que por otros nombres tiene los de Marcos de Colonia y Burgalés, sirve para pesar el oro, la plata y otras alhajas. Se compone de 8 onzas; pero la onza se divide en otras diferentes pesas, que se verán mas claramente en la tabla siguiente.

Por aquí se ve que el Marco castellano para pesar la plata se divide en 4608 granos, y para pesar el oro en 4800 : por lo que debo prevenir, que para mayor uniformidad en esta obra me he servido siempre de la primer division; y así todas las veces que se trata en ella de granos del Marco castellano, ó so1amente de granos sin otra denominacion, se deberá entender de los que compone el Marco de plata.

The castellano that serves for assays of gold has 24 carats, the carat has 4 grános, and the grain 8 parts.

The marco for the assay of silver, is divided into 12 dineros, and each dinero into 24 granos.

By law worked silver must be 9 dineros. The alloys are sealed with different hallmarks.

The marco castellano, which is also called marco de Colonia and marco de Burgalés, serves to weigh gold, silver and other jewelry. It consists of 8 ounces, but the ounce is divided into other different weights, which will be more clearly seen in the table below.

Here we can see that to weigh silver the marco castellano is divided into 4608 grains and to weigh gold into 4800: so I must warn that for greater uniformity in this work I have always used the first division. And so whenever grains of the marco castellano are mentioned, or grains without any other denomination, grains of the marc of silver must be understood.

In Chile A map showing the location of Chile., ? – 19th century, a unit of mass equal to ¹⁄₁₀₀th of a libra, about 0.46 grams.

Since 2 marcs traditionally made a libra, this is essentially the same unit as the one above.
