Persian units of measurement
Ancient system of weights and measures
From Wikipedia, the free encyclopedia
An official system of weights and measures was established[citation needed] in the ancient Persian Empire under the Achaemenid dynasty (550–350 BCE). The shekel and mina ("profane" or "sacred") were units of both weight and volume. A shekel or mina weight was equal to the weight of that volume of water. The talent was a measure of weight used for large amounts of coinage. Some related units were used in Persia in the 19th century, and are still used in contemporary Iran.

Volume
The shekel and mina ("profane" or "sacred") were units of both weight and volume. A shekel or mina weight was equal to the weight of that volume of water. Note that the values given for the mina do not match the definitions.
- 1 shekel = 8.3 ml (approximately 1 cubic aiwas).
- 1 profane mina = 50 shekel = 500 ml (approximately 27 cubic aiwas).
- 1 sacred mina = 60 shekel = 600 ml (approximately 1 cubic dva).
- 1 talent (volume) = 60 profane mina = 25 liters (approximately 1 cubic trayas).
Weight
The talent was a measure of weight used for large amounts of coinage (bullion, bulk coin), rather than an individual coin. Seven Babylonian talents equalled ten Attic talents, according to a list of the revenues of Cyrus the Great recorded in Herodotus.[5][6]
𐎣𐎼𐏁 (karša) or 𐎣𐎼𐏁𐎹𐎠 (karšayā) is a unit of weight equal to 10 Babylonian shekels or 1⁄6 Babylonian mina weighing approximately 83 g (2.9 oz).[7]
