Units explained
Gerah (Biblical Hebrew)
The gerah was the smallest Hebrew weight, about 0.57 gram (one-twentieth of a shekel).
From a Hebrew word for a small grain or bean.
Ancient Israelite metrology.
Part of the smallest divisions of the biblical shekel.
Microgram
A microgram (ug) equals 10^-9 kilogram, or one-millionth of a gram.
From the SI prefix 'micro-' (from Greek 'mikros', small).
Trace nutrients, potent drug doses, and environmental contaminant levels.
The micro- prefix was incorporated into the SI in 1960.

Worked examples
Example 1 — Convert 1 gerah to µg:
1 × 569999.9999999999 = 569999.9999999999 µg
Example 2 — Convert 100 gerah to µg:
100 × 569999.9999999999 = 5.7e+7 µg
Real-world example — Mid-micron to nanometer
3 gerahs (biblical hebrew) equals 3,000 micrograms — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 gerah × 569999.9999999999 = 1709999.9999999995 µg
Real-world example — From microns to sub-micron features
One gerah (biblical hebrew) equals one thousand micrograms — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 gerah × 569999.9999999999 = 569999.9999999999 µg
Real-world example — Infrared to visible-spectrum mapping
A 10-gerah (biblical hebrew) thermal infrared wavelength corresponds to a much larger number in micrograms, the unit favoured for ultraviolet and visible-light specifications.
10 gerah × 569999.9999999999 = 5699999.9999999991 µg
