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) = 9.842065e-16 Long Ton (UK) (ton (UK)).

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 long ton (imperial ton) is a unit of mass equal to 2,240 pounds or approximately 1,016 kilograms.
1 long ton = 2,240 lb = 1,016.047 kg = 1.016 metric tonnes = 1.12 short tons.
To convert long tons to kg: multiply by 1,016.047. To convert long tons to short tons: multiply by 1.12.
Ship displacement tonnage (historical, some naval vessels still use it), and some UK agricultural contexts.
Naval ship displacement is traditionally given in long tons. HMS Titanic displaced about 52,310 long tons.
Assuming a 'ton' is a 'ton' — the long ton is 12% heavier than a short ton and 1.6% heavier than a metric tonne.
Easy memory: Long ton = British = 2,240 lb (long = larger). Short ton = US = 2,000 lb (short = smaller).
