Carbon-12 Atom Mass

What is a carbon-12 atom mass?

The mass of a single carbon-12 atom is exactly 12 u by definition, about 1.9926E-26 kg.

Origin of the carbon-12 atom mass

The reference nuclide that defines the unified atomic mass scale.

Where it is used

The defining standard for the atomic mass unit.

When and where it was developed

Chosen as the mass standard by IUPAC and IUPAP in 1960-1961.

Biblical / Ancient

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.

Carbon-12 Atom Mass to Gerah (Biblical Hebrew) 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 carbon-12 atom mass and gerahs (biblical hebrew):

1 C-12 = 3.495872e-23 gerah

1 gerah = 2.860517e+22 C-12

To convert carbon-12 atom mass to gerahs (biblical hebrew), multiply the value in carbon-12 atom mass by 3.495872e-23. To reverse, multiply gerahs (biblical hebrew) by 2.860517e+22.

How to use this converter

Type a value into the calculator. The result in gerahs (biblical hebrew) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Gerah (Biblical Hebrew) to Carbon-12 Atom Mass converter for the reverse direction.

Step-by-step: convert carbon-12 atom mass to gerahs (biblical hebrew)

Write down the value in carbon-12 atom mass (C-12).
Multiply that value by the factor 3.495872e-23.
The product is the equivalent value in gerahs (biblical hebrew) (gerah).
To reverse, multiply the gerah (biblical hebrew) value by 2.860517e+22.

Worked examples

Example 1 — Convert 1 C-12 to gerah:
1 × 3.495872e-23 = 3.495872e-23 gerah

Example 2 — Convert 100 C-12 to gerah:
100 × 3.495872e-23 = 3.495872e-21 gerah

Real-world example — Spanning sub-micron to micron scale

Crossing from carbon-12 atom mass to gerahs (biblical hebrew) is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 carbon-12 atom mass translates to a much more compact value in gerahs (biblical hebrew) that fits the scale of biological cells and process nodes.

1000 C-12 × 3.495872e-23 = 3.495872e-20 gerah

Real-world example — Sub-visible-light wavelength

500 carbon-12 atom mass (the green-yellow visible band) equals 0.5 gerahs (biblical hebrew) — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.

500 C-12 × 3.495872e-23 = 1.747936e-20 gerah
