Danik ( Arabic: دَانِقٌ ) - Egyptian measure of area (surface) adopted after 1830.
The Egyptians had a standard unit of length - ( lat. Cubitum ) elbow. Ancient metrology did not know a more common measure of length than an "elbow" until more accuracy was required. The elbow is "the part of the hand is always with you and was convenient to use ."
The English archaeologist - Egyptologist G. Carter discovered an interesting object in the tomb of Tutankhamun - a luxurious case. Upon further research, it turned out that the Egyptian standard of length, the sacred elbow, was stored in this case. It was equal to the distance from the elbow to the end of the middle finger of the outstretched arm. Initially, the “royal elbow” in Egypt was 0. 525 m. After 1830, the average size of the Hashimi (Zira) elbow , equal to 66.5 cm, was adopted in Egypt.
1 Danik = 4 Sahma = 1/2 Hubba = 1/6 of Kirate = 1/144 Faddana = 29.172 m² = 66 square meters the elbows of Hashimi (Zira) [1] [2] .
