How to Convert Dalton to Metric Ton
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-30 Metric Ton (t).

About Dalton (Da)
Definition
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.
Mathematical Relationship
1 Da = 1 u = 1.6605390666 × 10⁻²⁷ kg. Proteins range from ~5 kDa to >1,000 kDa.
Conversion Formula
To convert Da to kg: multiply by 1.6605390666 × 10⁻²⁷. 1 kDa = 1,000 Da.
Practical Applications
Protein molecular weights (hemoglobin ≈ 64.5 kDa), DNA fragment sizing, and antibody characterization.
Interesting Facts
Titin, the largest known protein, has a molecular weight of about 3,800 kDa (3.8 MDa). The average protein is ~40–50 kDa.
Common Mistakes
The dalton and u are identical — they're just preferred in different fields (Da in biology, u in chemistry/physics).
Educational Tips
If a paper says a protein is '50 kDa,' that's 50,000 atomic mass units — about 50,000 hydrogen atoms' worth of mass.
About Metric Ton (t)
Definition
The metric ton (tonne) is a unit of mass equal to 1,000 kilograms or one megagram.
Mathematical Relationship
1 t = 1,000 kg = 10⁶ g = 2,204.62 lb = 1.10231 short tons = 0.98421 long tons.
Conversion Formula
To convert tonnes to kg: multiply by 1,000. To convert tonnes to short tons: multiply by 1.10231.
Practical Applications
Cargo shipping, vehicle weight ratings, construction material ordering, and agricultural harvests.
Interesting Facts
The three 'tons' often cause confusion: metric tonne (1,000 kg), short ton (907 kg, US), and long ton (1,016 kg, UK).
Common Mistakes
Confusing metric tonnes with short tons (US) or long tons (UK). A metric tonne is 10% heavier than a US short ton.
Educational Tips
1 tonne = ~2,200 lb. Quick check: multiply tonnes by 2.2 to get approximate thousands of pounds.
