Dans les gros payemens on ne compte pas par Ticals, mais par Taels & par Catez: Le Tael est composé de quatre Ticals, & le Caté de vingt Taels.

Le Caté & le Pique sont les Mesures les plus ordinaires du Pays: Le Caté pese trois livres & une once, & le Pique pese trois Catez. La plus grande mesure du Ris qu'ils appellent Coïa, contient quarante autres petites Mesures, dont chacune est du poids de cent Catez.

Large payments are not made in *ticals*, but in *
taels* or *catties*. The
*tael* is composed of 4 *ticals*, and the catty of 20 *taels*.

The *catty* and the *picul
*are the most common measures of the country. The catty weighs 3 livres, 1 once, and the *picul* weighs 3 catties. The largest rice measure, called a coïa, contains 40 other small measures, each of which weighs 100 catties.

Three *livres*, 1 *once poids de marc* would be
about 1499.1 grams, which is much larger than the Chinese catty, and
significantly larger than the *chang*. We know of no other mentions of a 3-catty
*picul*, nor the identity of the 4000-catty unit.

An FAO publication states: “100 tai cattles = 60 Kg.” We interpret this as clerical errors distorting “100 Taiwanese catties = 60 kg,” that is, the catty in Taiwan is 600 grams.
