Egyptian Royal Cubit

The Egyptian Royal Cubit is an ancient unit of length measurement used in Egypt, approximately 20.63 inches (52.35 centimeters). It was based on the length of a person's forearm, from the elbow to the tip of the middle finger. The Royal Cubit was a standard tool for construction, record-keeping, and engineering in ancient Egypt, ensuring consistency across projects like pyramids and temples. Although its exact length varied slightly over time, it remains an important reference in archaeology and the study of ancient Egyptian engineering and measurement systems.
