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.

Indian / South Asian

Tola

What is a tola?

The tola equals 180 troy grains, about 11.6638 grams (three-eighths of a troy ounce).

Origin of the tola

From Sanskrit 'tula', meaning a balance or weighing.

Where it is used

The primary unit for gold and silver across India, Pakistan, and Nepal.

When and where it was developed

Fixed at 180 grains under British India in 1833.

Carbon-12 Atom Mass to Tola 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 tolas:

1 C-12 = 1.708402e-24 tola
1 tola = 5.853422e+23 C-12

To convert carbon-12 atom mass to tolas, multiply the value in carbon-12 atom mass by 1.708402e-24. To reverse, multiply tolas by 5.853422e+23.

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

  1. Write down the value in carbon-12 atom mass (C-12).
  2. Multiply that value by the factor 1.708402e-24.
  3. The product is the equivalent value in tolas (tola).
  4. To reverse, multiply the tola value by 5.853422e+23.

Worked examples

Example 1 — Convert 1 C-12 to tola:
1 × 1.708402e-24 = 1.708402e-24 tola

Example 2 — Convert 100 C-12 to tola:
100 × 1.708402e-24 = 1.708402e-22 tola

Real-world example — From wavelengths to millimeter-scale objects

A value of one million carbon-12 atom mass sounds vast at the atomic scale but converts to a small everyday quantity in tolas — useful when relating optical-wavelength specifications to physical mounting hardware.

1000000 C-12 × 1.708402e-24 = 1.708402e-18 tola

Real-world example — Sub-micron to millimeter

500,000 carbon-12 atom mass converts to a small everyday quantity in tolas — useful when relating optical-wavelength specifications to physical mounting hardware.

500000 C-12 × 1.708402e-24 = 8.542011e-19 tola
