ỉtrw

In ancient Egypt, a unit of distance, = 20,000 schesup, about 10.46 kilometers (about 6.5 miles). Also romanized as iteru and jtrw.

The word also meant “river,” and in concept an ỉtrw was the distance a boat could be towed along the Nile River in one day. It was also used to describe distances over land, however.
