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.
Picogram
A picogram (pg) equals 10^-15 kilogram.
From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).
Single-cell biology and ultratrace chemical analysis.
The pico- prefix entered the SI in 1960.

Worked examples
Example 1 — Convert 1 gerah to pg:
1 × 5.7e+11 = 5.7e+11 pg
Example 2 — Convert 100 gerah to pg:
100 × 5.7e+11 = 5.7e+13 pg
Real-world example — Infrared to visible-spectrum mapping
A 10-gerah (biblical hebrew) thermal infrared wavelength corresponds to a much larger number in picograms, the unit favoured for ultraviolet and visible-light specifications.
10 gerah × 5.7e+11 = 5.7e+12 pg
Real-world example — Mid-micron to nanometer
3 gerahs (biblical hebrew) equals 3,000 picograms — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 gerah × 5.7e+11 = 1.71e+12 pg
Real-world example — From microns to sub-micron features
One gerah (biblical hebrew) equals one thousand picograms — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 gerah × 5.7e+11 = 5.7e+11 pg
