Ancient Egypt was one of the first civilizations to have a measurement system for lengths, weights and volumes. The ancient Egyptian measurement system contained units of length measurement, which is documented from the early dynasties period in the era of the ancient Egyptians.
Although it dates back to the Egyptian Fifth Dynasty, the Palermo stone recorded the level of the Nile River during the early dynasty era of King Jager, when the height of the Nile was recorded as 6 cubits and one palm (about 3,217 m or 10 feet 6.7 inches).
Land area records also go back to the Early Dynastic period where the Palermo Stone records the granting of land expressed as 'kha' and 'stat'. Mathematical papyri also include land area units.
Weights have been known since the ancient Egyptian kingdom and perhaps as early as the early dynastic period. Weights were measured in a unit called diben, and this unit was equivalent to 13.6 grams in the Old Kingdom, Middle Kingdom, and during the New Kingdom, it was equivalent to 91 grams.
The Palermo Stone is the largest of the seven remaining parts of a large memorial plaque known as the "Royal Annals of the Old State", which contains the list of the kings of Egypt from the era of the First Dynasty to the beginning of the Fifth Dynasty era, and records important events in each year of their rule, and it is believed that The painting was carved during the Fifth Dynasty era and the stone is kept in the Regional Archaeological Museum in Palermo, and the rest of the painting is in the museums of Cairo and London. Carved on a black basalt stone tablet, near the end of the Fifth Dynasty, the tablet lists the kings of ancient Egypt after the unification of Lower and Upper Egypt, starting with King Narmer, and is preserved today in the Antonio Salinas Regional Archeology Museum in Palermo, Italy, from which it takes its name.
