Units explained
Dekagram
A dekagram (dag) equals 0.01 kilogram, or 10 grams.
From the SI prefix 'deka-' (from Greek 'deka', ten).
Widely used in Central and Eastern European cooking and shops (dag/dkg).
Part of the original metric system introduced in 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.
Dekagram to Atomic Mass Unit conversion formula
The relationship between dekagrams and atomic mass unit:
To convert dekagrams to atomic mass unit, multiply the value in dekagrams by 6.022137e+24. To reverse, multiply atomic mass unit by 1.66054e-25.

Worked examples
Example 1 — Convert 1 dag to u:
1 × 6.022137e+24 = 6.022137e+24 u
Example 2 — Convert 100 dag to u:
100 × 6.022137e+24 = 6.022137e+26 u
Real-world example — Small-scale to atomic-scale
One dekagram equals 10 million atomic mass unit — useful for physics curricula that relate everyday measurements to atomic and optical scales.
1 dag × 6.022137e+24 = 6.022137e+24 u
Real-world example — Centimeter to wavelength scale
One dekagram equals 10 million atomic mass unit. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.
1 dag × 6.022137e+24 = 6.022137e+24 u
