ancient Egyptian unit of measurement

Quick Summary

The ancient Egyptian cubit was a primary unit of linear measurement, developed around 3000 BCE. It was based on the length of the arm from the elbow to the fingertips. A royal master cubit served as the standard, with all other cubit sticks measured against it. The royal cubit measured 524 mm (20.62 inches) and was divided into 28 digits (fingerbreadths). A "large span" was equivalent to 14 digits, or half a cubit. The Egyptians also developed methods for land measurement, crucial due to the annual flooding of the Nile River.12
