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
Quadrans (Biblical Roman)
The quadrans was a small Roman bronze coin used during the Roman Empire, including the Biblical era. It was worth one-quarter of an as and served as one of the lowest denominations in Roman currency.
The quadrans was commonly used for everyday small purchases and minor transactions. Its low value made it accessible to ordinary people for daily needs.
Though rarely mentioned explicitly in the Bible, the quadrans was part of the coinage system during the time of Jesus and the Roman occupation.
Summary:
Roman bronze coin worth ¼ of an as
Used for small, everyday transactions
Part of the Roman currency system in Biblical times
