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-17 Decigram (dg).

| 0.1 | 1.000000e-18 |
| 0.5 | 5.000000e-18 |
| 1 | 1.000000e-17 |
| 2 | 2.000000e-17 |
| 5 | 5.000000e-17 |
| 10 | 1.000000e-16 |
| 25 | 2.500000e-16 |
| 50 | 5.000000e-16 |
| 100 | 1.000000e-15 |

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 decigram is a unit of mass equal to one tenth of a gram (10⁻¹ g) or 100 milligrams.
1 dg = 0.1 g = 100 mg = 10 cg.
To convert dg to grams: divide by 10. To convert dg to mg: multiply by 100.
Limited modern use. May appear in some European cooking recipes or educational worksheets.
The decigram was in wider use in the 19th century when the metric system was still establishing conventions.
Confusing dg (decigram) with dag (dekagram) — they differ by a factor of 100.
Deci = one-tenth, deka = ten. They are opposite: dg = 0.1 g, dag = 10 g.
