The unit of weight used in Ancient Egypt was the deben. It was equal to 91 grams and was divided into 10 parts. Bread was weighted by the loaf, which weighed between 28 and 33 ounces.
Liquids were measured by the jar, which was the equivalent of .13 of a gallon. Cereals were measured by the barrel, corresponding to nearly 1.1 gallon. Length was measured in royal cubits divided into 28 fingers, or the length of the arm from the end of the middle finger to the elbow. There was also a small cubit, used by architects and divided into 24 fingers.
Egyptians calculated distances in units of 20,000 cubits, which would be the equivalent of 6.5 miles. They measured area in a unit equal to 100 square cubits, or 29,440 square feet.
