Gerah (Biblical Hebrew)
The gerah was the smallest unit of weight in ancient Biblical Hebrew measurement systems. It is traditionally considered 1/20 of a shekel.
Since a shekel weighed about 11 grams, a gerah would weigh roughly 0.55 grams. The gerah was used to measure small amounts of precious metals like silver and gold, important in commerce and religious rituals.
Summary:
1 gerah = 1/20 shekel ≈ 0.55 grams
