Mithkal

The mithkal or sextula (in Persian and Arabic: مثقال) is a unit of weight used in Iran, mostly for weighing gold. It is equivalent to a little over 4.5 grams.^[1] The word mithkal is sometimes also used to mean a very small amount, due to its use in the Quran in this way.^{[citation needed]}
