Gerah (Biblical Hebrew)

What is a gerah (biblical hebrew)?

The gerah was the smallest Hebrew weight, about 0.57 gram (one-twentieth of a shekel).

Origin of the gerah (biblical hebrew)

From a Hebrew word for a small grain or bean.

Where it is used

Ancient Israelite metrology.

When and where it was developed

Part of the smallest divisions of the biblical shekel.

Scientific / Atomic

Proton Mass

What is a proton mass?

The proton rest mass is about 1.6726E-27 kg.

Origin of the proton mass

The mass of the proton, the positively charged nucleon.

Where it is used

Nuclear and particle physics, and chemistry.

When and where it was developed

Quantified after Rutherford identified the proton around 1917-1920.

Gerah (Biblical Hebrew) to Proton Mass conversion formula

Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.

The relationship between gerahs (biblical hebrew) and proton mass:

1 gerah = 3.407821e+23 mp
1 mp = 2.934426e-24 gerah

To convert gerahs (biblical hebrew) to proton mass, multiply the value in gerahs (biblical hebrew) by 3.407821e+23. To reverse, multiply proton mass by 2.934426e-24.

How to use this converter

Type a value into the calculator. The result in proton mass updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Proton Mass to Gerah (Biblical Hebrew) converter for the reverse direction.

Step-by-step: convert gerahs (biblical hebrew) to proton mass

  1. Write down the value in gerahs (biblical hebrew) (gerah).
  2. Multiply that value by the factor 3.407821e+23.
  3. The product is the equivalent value in proton mass (mp).
  4. To reverse, multiply the proton mass value by 2.934426e-24.

Worked examples

Example 1 — Convert 1 gerah to mp:
1 × 3.407821e+23 = 3.407821e+23 mp

Example 2 — Convert 100 gerah to mp:
100 × 3.407821e+23 = 3.407821e+25 mp

Real-world example — Infrared to visible-spectrum mapping

A 10-gerah (biblical hebrew) thermal infrared wavelength corresponds to a much larger number in proton mass, the unit favoured for ultraviolet and visible-light specifications.

10 gerah × 3.407821e+23 = 3.407821e+24 mp

Real-world example — Mid-micron to nanometer

3 gerahs (biblical hebrew) equals 3,000 proton mass — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 gerah × 3.407821e+23 = 1.022346e+24 mp

Real-world example — From microns to sub-micron features

One gerah (biblical hebrew) equals one thousand proton mass — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 gerah × 3.407821e+23 = 3.407821e+23 mp
