Gamma
The gamma (γ) is a very small unit of mass used mainly in geophysics, soil science, and radiology. It is equivalent to one microgram (1 µg) or 10⁻⁶ grams.
The term "gamma" is often used to express trace amounts of substances or contaminants in samples, helping scientists measure extremely small quantities with precision.
Summary:
1 gamma = 1 microgram = 10⁻⁶ grams
Used in soil science, geophysics, and radiological measurements
Ideal for quantifying very tiny masses
Drachma (Biblical Greek)
The drachma was a standard silver coin and unit of currency in ancient Greece during Biblical times. It was widely used for trade and everyday transactions.
A single drachma typically weighed about 4.3 grams of silver. It served as the basic monetary unit, with larger denominations like the didrachma (2 drachmas) and tetradrachma (4 drachmas) built upon it.
The drachma is frequently mentioned in historical and Biblical texts as a common currency in the Mediterranean region.

Ancient Greek silver coin weighing about 4.3 grams
Basic unit of currency in Biblical Greek times
Foundation for larger denominations like didrachma and tetradrachma
