To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
For example, 1 Attogram (ag) = 1.000000e-9 Nanogram (ng).
| Attogram (ag) | Nanogram (ng) |
|---|---|
| 0.1 | 1.000000e-10 |
| 0.5 | 5.000000e-10 |
| 1 | 1.000000e-9 |
| 2 | 2.000000e-9 |
| 5 | 5.000000e-9 |
| 10 | 1.000000e-8 |
| 25 | 2.500000e-8 |
| 50 | 5.000000e-8 |
| 100 | 1.000000e-7 |
| 500 | 5.000000e-7 |
| 1000 | 0.000001 |
The attogram is a unit of mass equal to 10⁻¹⁸ grams or 10⁻²¹ kilograms — one quintillionth of a gram.
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
Measuring masses of individual nanoparticles, viruses, and large biomolecules in nanosensor research.
In 2012, researchers achieved single-proton sensitivity (1.67 × 10⁻⁶ ag) using carbon nanotube resonators.
Confusing atto (10⁻¹⁸) with femto (10⁻¹⁵) — they differ by a factor of 1,000.
Follow the prefix chain down: milli, micro, nano, pico, femto, atto — each step is 1,000× smaller.
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.
