Atomic Mass Unit

What is a atomic mass unit?

One unified atomic mass unit (u) is defined as 1/12 the mass of a carbon-12 atom, about 1.6605E-27 kg.

Origin of the atomic mass unit

Introduced to give atomic and molecular masses convenient numerical values.

Where it is used

Atomic, molecular, and nuclear physics and chemistry.

When and where it was developed

The unified (carbon-12) scale was adopted by IUPAC and IUPAP in 1960-1961.

Avoirdupois

Ton (short, US)

What is a ton (short, us)?

The short (US) ton equals 2,000 pounds, about 907 kilograms.

Origin of the ton (short, us)

The American ton, equal to 20 short hundredweight.

Where it is used

US industry, mining, and commodity output.

When and where it was developed

Standardized within US customary units.

Atomic Mass Unit to Ton (short, US) conversion formula

The relationship between atomic mass unit and tons (short, us):

1 u = 1.830432e-30 sh tn
1 sh tn = 5.46319e+29 u

To convert atomic mass unit to tons (short, us), multiply the value in atomic mass unit by 1.830432e-30. To reverse, multiply tons (short, us) by 5.46319e+29.

How to use this converter

Type a value into the calculator. The result in tons (short, us) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Ton (short, US) to Atomic Mass Unit converter for the reverse direction.

Step-by-step: convert atomic mass unit to tons (short, us)

  1. Write down the value in atomic mass unit (u).
  2. Multiply that value by the factor 1.830432e-30.
  3. The product is the equivalent value in tons (short, us) (sh tn).
  4. To reverse, multiply the ton (short, us) value by 5.46319e+29.

Worked examples

Example 1 — Convert 1 u to sh tn:
1 × 1.830432e-30 = 1.830432e-30 sh tn

Example 2 — Convert 100 u to sh tn:
100 × 1.830432e-30 = 1.830432e-28 sh tn

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 atomic mass unit can be re-expressed in tons (short, us) for direct comparison with another instrument's calibration data sheet.

800 u × 1.830432e-30 = 1.464346e-27 sh tn

Real-world example — Molecular dimensions

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

2 u × 1.830432e-30 = 3.660864e-30 sh tn
