How to Convert Dalton to Gram
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-24 Gram (g).

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 Gram (g)
Definition
The gram is a metric unit of mass equal to one thousandth of a kilogram, originally defined as the mass of one cubic centimeter of water at 4°C.
Mathematical Relationship
1 g = 0.001 kg = 1,000 mg = 10⁶ µg. There are 453.59 g in one pound.
Conversion Formula
To convert grams to ounces: divide by 28.3495. To convert grams to pounds: divide by 453.592.
Practical Applications
Cooking recipes, food nutrition labels, postal weight limits, jewelry, and chemistry lab measurements.
Interesting Facts
A US dollar bill weighs approximately 1 g. A standard paper clip also weighs about 1 g.
Common Mistakes
Confusing grams with ounces — 1 oz ≈ 28.35 g, not 1 g. Also, mixing up g (gram) with G (giga prefix).
Educational Tips
A paper clip = ~1 g, a nickel = 5 g, a banana = ~120 g. Build intuition with everyday objects.
