A Seer (also sihr) is a traditional unit of mass and volume used in large parts of Asia prior to the middle of the 20th century. It remains in use only in a few countries such as Afghanistan, Iran, and parts of India although in Iran it indicates a smaller unit of weight than the one used in India.
