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.
Carbon-12 Atom Mass
The mass of a single carbon-12 atom is exactly 12 u by definition, about 1.9926E-26 kg.
The reference nuclide that defines the unified atomic mass scale.
The defining standard for the atomic mass unit.
Chosen as the mass standard by IUPAC and IUPAP in 1960-1961.

Worked examples
Example 1 — Convert 1 dg to C-12:
1 × 5.018451e+21 = 5.018451e+21 C-12
Example 2 — Convert 100 dg to C-12:
100 × 5.018451e+21 = 5.018451e+23 C-12
Real-world example — From microns to sub-micron features
One decigram equals one thousand carbon-12 atom mass — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 dg × 5.018451e+21 = 5.018451e+21 C-12
Real-world example — Infrared to visible-spectrum mapping
A 10-decigram thermal infrared wavelength corresponds to a much larger number in carbon-12 atom mass, the unit favoured for ultraviolet and visible-light specifications.
10 dg × 5.018451e+21 = 5.018451e+22 C-12
Real-world example — Mid-micron to nanometer
3 decigrams 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 dg × 5.018451e+21 = 1.505535e+22 C-12
