How to Convert Atomic Mass Unit to Dekagram
To convert u to kg: multiply by 1.6605390666 × 10⁻²⁷. To convert u to MeV/c²: multiply by 931.494.
1 u = 1.6605390666 × 10⁻²⁷ kg = 1/Nₐ grams ≈ 931.494 MeV/c².
For example, 1 Atomic Mass Unit (u) = 1.660539e-25 Dekagram (dag).

About Atomic Mass Unit (u)
Definition
The atomic mass unit (unified) is defined as 1/12 the mass of a carbon-12 atom, approximately 1.661 × 10⁻²⁷ kilograms.
Mathematical Relationship
1 u = 1.6605390666 × 10⁻²⁷ kg = 1/Nₐ grams ≈ 931.494 MeV/c².
Conversion Formula
To convert u to kg: multiply by 1.6605390666 × 10⁻²⁷. To convert u to MeV/c²: multiply by 931.494.
Practical Applications
Molecular weight calculations, mass spectrometry data interpretation, and chemical stoichiometry.
Interesting Facts
A proton has a mass of ~1.007 u, a neutron ~1.009 u. The discrepancy from 1.000 reflects nuclear binding energy.
Common Mistakes
Confusing 'amu' (the old, obsolete term) with 'u' (the unified standard). Also, forgetting that 1 u ≠ 1 gram.
Educational Tips
Think of u as 'approximately the mass of one proton or neutron.' Carbon-12 = 12 u exactly (by definition).
About Dekagram (dag)
Definition
The dekagram (decagram) is a unit of mass equal to 10 grams.
Mathematical Relationship
1 dag = 10 g = 0.01 kg = 10,000 mg.
Conversion Formula
To convert dag to grams: multiply by 10. To convert dag to kg: divide by 100.
Practical Applications
Common at European delis and markets: '15 dag of cheese' means 150 g. Used in Austrian recipes.
Interesting Facts
In Austria and parts of Italy, the dekagram ('deka') is the default unit at deli counters — more common there than grams.
Common Mistakes
Not recognizing 'dag' or 'dkg' outside Europe. Converting: remember dag = 10 g, not 100 g.
Educational Tips
If you travel to Austria, 'ein Deka' at the deli means 10 grams. 10 Deka = 100 g.
