Cubit

American Tract Society Bible Dictionary

A measure used among the ancients. A cubit was originally the distance from the elbow to the extremity of the middle finger, which is the fourth part of a well-proportioned man's stature. The Hebrew cubit, according to some, is twenty-one inches; but others fix it at eighteen. The Talmudists observe that the Hebrew cubit was larger by one quarter than the Roman.
