The aim of this article is to broaden our knowledge of the metrological system of the Morisco period in the kingdom of Granada and, more specifically, in the rural area of the Alpujarra. The sources used in the analysis are two inventories of ecclesiastical goods from Islamic origin, drawn up in 1527 and 1530, four decades after the culmination of the Christian conquest of al-Andalus. The article explores the agrarian units of measurement used by the Morisco community of the Alpujarra in their daily lives (measures of surface area and length, weight or mass, volume or capacity, and of water used for irrigation). As far as possible, equivalences are presented for the units discussed. Attempts are made to establish whether these measures were inherited from the Andalusi period or whether, on the contrary, they were the result of the implementation of Castilian legislation on the matter. The data gathered have revealed the existence of a hybrid measurement system, which shows that the ordinances to modify the system of weights and measures of the Muslims and to seek a correspondence with the Castilian system had little effect in the Alpujarra, where, in many cases, the Islamic system of measurement continued in use. This circumstance indicates that the changes and transformations in the daily life of this rural community after the Christian conquest were not as imminent as might have been expected.
