To convert short tons to kg: multiply by 907.185. To convert short tons to metric tonnes: multiply by 0.9072.
1 short ton = 2,000 lb = 907.18474 kg = 0.90718 metric tonnes.
For example, 1 Short Ton (US) (ton (US)) = 5.463194e+29 Dalton (Da).

The short ton (US ton) is a unit of mass equal to 2,000 pounds or approximately 907.185 kilograms.
1 short ton = 2,000 lb = 907.18474 kg = 0.90718 metric tonnes.
To convert short tons to kg: multiply by 907.185. To convert short tons to metric tonnes: multiply by 0.9072.
Coal mining output, grain production, truck payload limits, and US shipping and freight.
The US short ton (2,000 lb) is about 10% lighter than a metric tonne (2,205 lb) and about 11% lighter than a UK long ton (2,240 lb).
Assuming 'ton' means the same thing everywhere. In the US it's 2,000 lb; in the UK it's 2,240 lb; in metric it's 2,205 lb.
Remember: short ton = 2,000 lb, long ton = 2,240 lb, metric tonne = 2,205 lb. The metric tonne is between the other two.
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.
