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.

Point (1/100 carat) to Carbon-12 Atom Mass conversion formula

The relationship between points (1/100 carat) and carbon-12 atom mass:

1 pt = 1.00369e+20 C-12
1 C-12 = 9.963234e-21 pt

To convert points (1/100 carat) to carbon-12 atom mass, multiply the value in points (1/100 carat) by 1.00369e+20. To reverse, multiply carbon-12 atom mass by 9.963234e-21.

Step-by-step: convert points (1/100 carat) to carbon-12 atom mass

  1. Write down the value in points (1/100 carat) (pt).
  2. Multiply that value by the factor 1.00369e+20.
  3. The product is the equivalent value in carbon-12 atom mass (C-12).
  4. To reverse, multiply the carbon-12 atom mass value by 9.963234e-21.

Worked examples

Example 1 — Convert 1 pt to C-12:
1 × 1.00369e+20 = 1.00369e+20 C-12

Example 2 — Convert 100 pt to C-12:
100 × 1.00369e+20 = 1.00369e+22 C-12

Real-world example — Infrared to visible-spectrum mapping

A 10-point (1/100 carat) thermal infrared wavelength corresponds to a much larger number in carbon-12 atom mass, the unit favoured for ultraviolet and visible-light specifications.

10 pt × 1.00369e+20 = 1.00369e+21 C-12

Real-world example — Mid-micron to nanometer

3 points (1/100 carat) equals 3,000 carbon-12 atom mass — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 pt × 1.00369e+20 = 3.01107e+20 C-12

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

One point (1/100 carat) equals one thousand carbon-12 atom mass — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 pt × 1.00369e+20 = 1.00369e+20 C-12
