How to Convert Atomic Mass Unit to Decigram
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-23 Decigram (dg).

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 Decigram (dg)
Definition
The decigram is a unit of mass equal to one tenth of a gram (10⁻¹ g) or 100 milligrams.
Mathematical Relationship
1 dg = 0.1 g = 100 mg = 10 cg.
Conversion Formula
To convert dg to grams: divide by 10. To convert dg to mg: multiply by 100.
Practical Applications
Limited modern use. May appear in some European cooking recipes or educational worksheets.
Interesting Facts
The decigram was in wider use in the 19th century when the metric system was still establishing conventions.
Common Mistakes
Confusing dg (decigram) with dag (dekagram) — they differ by a factor of 100.
Educational Tips
Deci = one-tenth, deka = ten. They are opposite: dg = 0.1 g, dag = 10 g.
