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

Nanogram

What is a nanogram?

A nanogram (ng) equals 10^-12 kilogram.

Origin of the nanogram

From the SI prefix 'nano-' (from Greek 'nanos', dwarf).

Where it is used

Molecular biology, forensics, and toxicology.

When and where it was developed

The nano- prefix entered the SI in 1960.

Carbon-12 Atom Mass to Nanogram conversion formula

The relationship between carbon-12 atom mass and nanograms:

1 C-12 = 1.992647e-14 ng
1 ng = 5.018451e+13 C-12

To convert carbon-12 atom mass to nanograms, multiply the value in carbon-12 atom mass by 1.992647e-14. To reverse, multiply nanograms by 5.018451e+13.

How to use this converter

Type a value into the calculator. The result in nanograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Nanogram to Carbon-12 Atom Mass converter for the reverse direction.

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

  1. Write down the value in carbon-12 atom mass (C-12).
  2. Multiply that value by the factor 1.992647e-14.
  3. The product is the equivalent value in nanograms (ng).
  4. To reverse, multiply the nanogram value by 5.018451e+13.

Worked examples

Example 1 — Convert 1 C-12 to ng:
1 × 1.992647e-14 = 1.992647e-14 ng

Example 2 — Convert 100 C-12 to ng:
100 × 1.992647e-14 = 1.992647e-12 ng

Real-world example — Molecular dimensions

The diameter of small molecular structures (around 2 carbon-12 atom mass) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.

2 C-12 × 1.992647e-14 = 3.985294e-14 ng

Real-world example — Wavelengths across the spectrum

Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 carbon-12 atom mass can be re-expressed in nanograms for direct comparison with another instrument's calibration data sheet.

800 C-12 × 1.992647e-14 = 1.594118e-11 ng
