The Greeks measured length roughly the way the Egyptians did: a daktylos is a finger-joint, or inch; a pous is a foot, or 12 inches; a pēchys is a cubit, half a yard, or 18 inches. Longer distances were a bēma, a pace, 5 feet; an orgyia, a fathom, 6 feet; a stadion, 600 feet (an eighth of a mile); a milion, a mile.
