Traditional Tatar units of measurement were used by Tatars until 1924 but became obsolete when the Soviet Union adopted the metric system. The Tatar system shares many units with the Russian system (e.g. and ), which is close to the English (The Russian system existed since ancient Rus', but under Peter the Great, the Russian units were redefined relative to the English system.), therefore a is relatively equal to an inch. This list includes their Tatar language names.
