The se'ah or seah (Hebrew: סאה sə’āh), plural se'im, is a unit of dry measure of ancient origin found in the Bible and in Halakha (Jewish law), which equals one third of an ephah, or bath. In layman's terms, it is equal to the capacity of 144 medium-sized eggs, or what is equal in volume to about 9 US quarts (8.5 litres).[1] Its size in modern units varies widely according to the criteria used for defining it.
