The pound is legally defined as exactly 0.45359237 kg worldwide since 1959. 'Pound' and British '£' both trace back to the Roman libra.
Confusing pounds (mass) with pound-force (a unit of force). Also, approximately 1 kg = 2.2 lb, not 2 lb.
Quick rule: divide pounds by 2 and subtract 10% for a rough kg conversion. Example: 150 lb ÷ 2 = 75, minus 10% ≈ 68 kg.
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.
