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.
Planck Mass
The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.
Introduced by Max Planck in 1899 as part of a system of natural units.
Theoretical physics and quantum-gravity research.
Defined by Planck in 1899 from fundamental constants.

Worked examples
Example 1 — Convert 1 gerah to mP:
1 × 26186.3086952327 = 26186.3086952327 mP
Example 2 — Convert 100 gerah to mP:
100 × 26186.3086952327 = 2618630.869523271 mP
Real-world example — From microns to sub-micron features
One gerah (biblical hebrew) equals one thousand planck mass — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 gerah × 26186.3086952327 = 26186.3086952327 mP
Real-world example — Infrared to visible-spectrum mapping
A 10-gerah (biblical hebrew) thermal infrared wavelength corresponds to a much larger number in planck mass, the unit favoured for ultraviolet and visible-light specifications.
10 gerah × 26186.3086952327 = 261863.0869523271 mP
Real-world example — Mid-micron to nanometer
3 gerahs (biblical hebrew) equals 3,000 planck mass — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 gerah × 26186.3086952327 = 78558.9260856981 mP
