Units explained
Decigram
A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.
From the SI prefix 'deci-' (from Latin 'decimus', tenth).
Occasional laboratory and pharmacy use.
Part of the original metric system of 1795.
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.
Introduced to give atomic and molecular masses convenient numerical values.
Atomic, molecular, and nuclear physics and chemistry.
The unified (carbon-12) scale was adopted by IUPAC and IUPAP in 1960-1961.
Decigram to Atomic Mass Unit conversion formula
The relationship between decigrams and atomic mass unit:
To convert decigrams to atomic mass unit, multiply the value in decigrams by 6.022137e+22. To reverse, multiply atomic mass unit by 1.66054e-23.

Step-by-step: convert decigrams to atomic mass unit
- Write down the value in decigrams (dg).
- Multiply that value by the factor 6.022137e+22.
- The product is the equivalent value in atomic mass unit (u).
- To reverse, multiply the atomic mass unit value by 1.66054e-23.
Worked examples
Example 1 — Convert 1 dg to u:
1 × 6.022137e+22 = 6.022137e+22 u
Example 2 — Convert 100 dg to u:
100 × 6.022137e+22 = 6.022137e+24 u
Real-world example — Mid-micron to nanometer
3 decigrams equals 3,000 atomic mass unit — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 dg × 6.022137e+22 = 1.806641e+23 u
Real-world example — From microns to sub-micron features
One decigram equals one thousand atomic mass unit — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 dg × 6.022137e+22 = 6.022137e+22 u
Real-world example — Infrared to visible-spectrum mapping
A 10-decigram thermal infrared wavelength corresponds to a much larger number in atomic mass unit, the unit favoured for ultraviolet and visible-light specifications.
10 dg × 6.022137e+22 = 6.022137e+23 u
