Cubit rod from the Turin Museum. Surveying and itinerant measurement were undertaken using rods, poles, and knotted cords of rope. A scene in the tomb of Menna in Thebes shows surveyors measuring a plot of land using rope with knots tied at regular intervals. Similar scenes can be found in the tombs of Amenhotep-Sesi, Khaemhat and Djeserkareseneb.
Flinders Petrie reported on a rod that shows a length of 520.5 mm, a few millimetres less than the Egyptian cubit. [8] A slate measuring rod was also found, divided into fractions of a Royal Cubit and dating to the time of Akhenaten. [9] Further cubit rods have been found in the tombs of officials.

[11] The royal cubit measured approximately 525 mm, [12] so the width of the ancient Egyptian hand was about 94 mm.
Some commentators upon Thom's megalithic yard (John Ivimy and then Euan Mackie [25]) have noted how such a measure could relate to geometrical ideas found historically in two Egyptian metrological units; the remen of about 1.2 feet and royal cubit of about 1.72 feet. The remen and royal cubit were used to define land areas in Egypt: "On ...
