How to Convert Dalton to Long Ton (UK)
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) = 1.634313e-30 Long Ton (UK) (ton (UK)).

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 Long Ton (UK) (ton (UK))
Definition
The long ton (imperial ton) is a unit of mass equal to 2,240 pounds or approximately 1,016 kilograms.
Mathematical Relationship
1 long ton = 2,240 lb = 1,016.047 kg = 1.016 metric tonnes = 1.12 short tons.
Conversion Formula
To convert long tons to kg: multiply by 1,016.047. To convert long tons to short tons: multiply by 1.12.
Practical Applications
Ship displacement tonnage (historical, some naval vessels still use it), and some UK agricultural contexts.
Interesting Facts
Naval ship displacement is traditionally given in long tons. HMS Titanic displaced about 52,310 long tons.
Common Mistakes
Assuming a 'ton' is a 'ton' — the long ton is 12% heavier than a short ton and 1.6% heavier than a metric tonne.
Educational Tips
Easy memory: Long ton = British = 2,240 lb (long = larger). Short ton = US = 2,000 lb (short = smaller).
