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) = 1.000000e-21 Teragram (Tg).
| Nanogram (ng) | Teragram (Tg) |
|---|---|
| 0.1 | 1.000000e-22 |
| 0.5 | 5.000000e-22 |
| 1 | 1.000000e-21 |
| 2 | 2.000000e-21 |
| 5 | 5.000000e-21 |
| 10 | 1.000000e-20 |
| 25 | 2.500000e-20 |
| 50 | 5.000000e-20 |
| 100 | 1.000000e-19 |
| 500 | 5.000000e-19 |
| 1000 | 1.000000e-18 |
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 teragram equals 10¹² grams or one million tonnes (one megatonne).
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
Global carbon budgets (~10,000 Tg C/year from fossil fuels), volcanic eruption plume masses.
Earth's atmosphere has a total mass of about 5.15 × 10⁶ Tg (5.15 × 10¹⁸ kg).
Confusing Tg with Pg (petagram): 1 Pg = 1,000 Tg. Climate papers use both — check carefully.
Global CO₂ emissions ≈ 36,000 Tg/year (or 36 Pg/year). This is a key climate number to remember.
