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.

Metric / SI

Decigram

What is a decigram?

A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.

Origin of the decigram

From the SI prefix 'deci-' (from Latin 'decimus', tenth).

Where it is used

Occasional laboratory and pharmacy use.

When and where it was developed

Part of the original metric system of 1795.

Carbon-12 Atom Mass to Decigram conversion formula

The relationship between carbon-12 atom mass and decigrams:

1 C-12 = 1.992647e-22 dg
1 dg = 5.018451e+21 C-12

To convert carbon-12 atom mass to decigrams, multiply the value in carbon-12 atom mass by 1.992647e-22. To reverse, multiply decigrams by 5.018451e+21.

Step-by-step: convert carbon-12 atom mass to decigrams

  1. Write down the value in carbon-12 atom mass (C-12).
  2. Multiply that value by the factor 1.992647e-22.
  3. The product is the equivalent value in decigrams (dg).
  4. To reverse, multiply the decigram value by 5.018451e+21.

Worked examples

Example 1 — Convert 1 C-12 to dg:
1 × 1.992647e-22 = 1.992647e-22 dg

Example 2 — Convert 100 C-12 to dg:
100 × 1.992647e-22 = 1.992647e-20 dg

Real-world example — Sub-visible-light wavelength

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

500 C-12 × 1.992647e-22 = 9.963234e-20 dg

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

Crossing from carbon-12 atom mass to decigrams 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 decigrams that fits the scale of biological cells and process nodes.

1000 C-12 × 1.992647e-22 = 1.992647e-19 dg
