How to Convert Attogram to Dalton
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
For example, 1 Attogram (ag) = 602214.0762 Dalton (Da).

About Attogram (ag)
Definition
The attogram is a unit of mass equal to 10⁻¹⁸ grams or 10⁻²¹ kilograms — one quintillionth of a gram.
Mathematical Relationship
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
Conversion Formula
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
Practical Applications
Measuring masses of individual nanoparticles, viruses, and large biomolecules in nanosensor research.
Interesting Facts
In 2012, researchers achieved single-proton sensitivity (1.67 × 10⁻⁶ ag) using carbon nanotube resonators.
Common Mistakes
Confusing atto (10⁻¹⁸) with femto (10⁻¹⁵) — they differ by a factor of 1,000.
Educational Tips
Follow the prefix chain down: milli, micro, nano, pico, femto, atto — each step is 1,000× smaller.
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.
