The yard is an example of a traditional unit originally defined as the distance from a person's nose to the tip of the finger extending furthest from his face when gthe arm is unstretched. Similar units have been found in other cultures, though half that unit (See Index of cubit-size units) or double that unit (See Index of fathom-size units) is also a common unit for measuring distances of that order of magnitude. This page gives a listing of yard-size units on this wiki.
