{{main|Ancient Mesopotamian units of measurement}}

In the classical [[Akkadian Empire]] system instituted in about 2250 BC during the reign of [[Naram-Sin of Akkad|Naram-Sin]], the finger was one-thirtieth of a cubit length. The cubit was equivalent to approximately 497&nbsp;mm, so the finger was equal to about 17&nbsp;mm. Basic length was used in architecture and field division.
