Measurements
Eorzeans measure length and distance in ilms, fulms, yalms, and malms.
The ilm is the fundamental unit of measurement, roughly equivalent to the length of an adult Hyuran thumb, with the longer fulms, yalms, and malms calcuated using the ilm as base.
History
In the year 986 of the Sixth Astral Era, a pirate who had come to Limsa Lominsa wanted to procure sailcloth from the black markets when his purchase fell short of the length for which he believed he had paid. Enraged, he incited a scuffle that left some fifty men dead or wounded. Admiral Agatzahr Roehmerslyn promptly arrested the pirate and lopped his thumb clean off, declaring that it would henceforth serve as the standard measure of an ilm throughout the land. Cast-iron replicas of the buccaneer's severed digit were produced in bulk and distributed around the realm to serve as one-ilm rules, and disputes over vague measurements soon became a thing of the past.[1]
