To convert ng to µg: divide by 1,000. To convert ng to grams: multiply by 10⁻⁹.
1 ng = 10⁻⁹ g = 10⁻¹² kg = 1,000 pg = 0.001 µg.
For example, 1 Nanogram (ng) = 6.022141e+14 Dalton (Da).

The nanogram is a unit of mass equal to 10⁻⁹ grams or 10⁻¹² kilograms — one billionth of a gram.
1 ng = 10⁻⁹ g = 10⁻¹² kg = 1,000 pg = 0.001 µg.
To convert ng to µg: divide by 1,000. To convert ng to grams: multiply by 10⁻⁹.
Drug dosing in ng/mL (blood levels), pesticide residue testing, and pollution monitoring (e.g., dioxin levels).
Many potent drugs are effective at blood concentrations of just a few ng/mL — a testament to how sensitive your body is.
Confusing ng/mL with µg/mL — a factor of 1,000 difference that can cause dangerous dosing errors in medicine.
Drug levels in blood are often in ng/mL — if someone says 'nanograms per milliliter', think trace-level drug monitoring.
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.
