Yxle

An yxle is the most common unit of distance-measurement in Cetaroth. It is a part of the noster system. Unlike the metric system's meter, the imperial system's inch and the marsisal system's unidome, the yxle can only be measured between realms. The measurement can not be measured physically, and is therefore the main way of measuring distance between realms.

Specifically, an yxle is the distance between two adjacent markers, during a central perfectum.
