To convert Da to kg: multiply by 1.6605390666 × 10⁻²⁷. 1 kDa = 1,000 Da.
1 Da = 1 u = 1.6605390666 × 10⁻²⁷ kg. Proteins range from ~5 kDa to >1,000 kDa.
For example, 1 Dalton (Da) = 1.660539e-23 Decigram (dg).

The dalton is a unit of mass equal to one unified atomic mass unit (1/12 of a carbon-12 atom), approximately 1.661 × 10⁻²⁷ kg.
1 Da = 1 u = 1.6605390666 × 10⁻²⁷ kg. Proteins range from ~5 kDa to >1,000 kDa.
To convert Da to kg: multiply by 1.6605390666 × 10⁻²⁷. 1 kDa = 1,000 Da.
Protein molecular weights (hemoglobin ≈ 64.5 kDa), DNA fragment sizing, and antibody characterization.
Titin, the largest known protein, has a molecular weight of about 3,800 kDa (3.8 MDa). The average protein is ~40–50 kDa.
The dalton and u are identical — they're just preferred in different fields (Da in biology, u in chemistry/physics).
If a paper says a protein is '50 kDa,' that's 50,000 atomic mass units — about 50,000 hydrogen atoms' worth of mass.
The decigram is a unit of mass equal to one tenth of a gram (10⁻¹ g) or 100 milligrams.
1 dg = 0.1 g = 100 mg = 10 cg.
To convert dg to grams: divide by 10. To convert dg to mg: multiply by 100.
Limited modern use. May appear in some European cooking recipes or educational worksheets.
The decigram was in wider use in the 19th century when the metric system was still establishing conventions.
Confusing dg (decigram) with dag (dekagram) — they differ by a factor of 100.
Deci = one-tenth, deka = ten. They are opposite: dg = 0.1 g, dag = 10 g.
