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-27 Exagram (Eg).
| Nanogram (ng) | Exagram (Eg) |
|---|---|
| 0.1 | 1.000000e-28 |
| 0.5 | 5.000000e-28 |
| 1 | 1.000000e-27 |
| 2 | 2.000000e-27 |
| 5 | 5.000000e-27 |
| 10 | 1.000000e-26 |
| 25 | 2.500000e-26 |
| 50 | 5.000000e-26 |
| 100 | 1.000000e-25 |
| 500 | 5.000000e-25 |
| 1000 | 1.000000e-24 |
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 exagram equals 10¹⁸ grams or 10¹⁵ kilograms — one trillion tonnes.
1 Eg = 10¹⁸ g = 10¹⁵ kg = 10⁹ tonnes.
To convert Eg to kg: multiply by 10¹⁵. To convert Eg to Pg: multiply by 1,000.
No everyday applications. Describes masses of small moons or large asteroids.
Earth's total mass is about 5.97 × 10⁶ Eg. The entire atmosphere weighs 'only' about 5 Eg.
Hardly ever encountered — most contexts use 'times 10^x kg' notation instead of exagrams.
If you need to express masses between Pg and Earth-masses, the exagram fills that gap: 1 Eg = 10¹⁵ kg.
