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.

Tael to Atomic Mass Unit 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 taels and atomic mass unit:

1 tael = 2.276329e+25 u
1 u = 4.393038e-26 tael

To convert taels to atomic mass unit, multiply the value in taels by 2.276329e+25. To reverse, multiply atomic mass unit by 4.393038e-26.

Step-by-step: convert taels to atomic mass unit

  1. Write down the value in taels (tael).
  2. Multiply that value by the factor 2.276329e+25.
  3. The product is the equivalent value in atomic mass unit (u).
  4. To reverse, multiply the atomic mass unit value by 4.393038e-26.

Worked examples

Example 1 — Convert 1 tael to u:
1 × 2.276329e+25 = 2.276329e+25 u

Example 2 — Convert 100 tael to u:
100 × 2.276329e+25 = 2.276329e+27 u

Real-world example — Centimeter to wavelength scale

One tael equals 10 million atomic mass unit. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.

1 tael × 2.276329e+25 = 2.276329e+25 u

Real-world example — Small-scale to atomic-scale

One tael equals 10 million atomic mass unit — useful for physics curricula that relate everyday measurements to atomic and optical scales.

1 tael × 2.276329e+25 = 2.276329e+25 u
