To liters: multiply by 10⁻¹⁸. To femtoliters: divide by 1,000. To cubic nanometers: 1 aL = 10⁶ nm³.
1 aL = 10⁻¹⁸ L = 10⁻²¹ m³ = 10⁻¹⁵ µL. One femtoliter = 1,000 aL.
For example, 1 Attoliter (aL) = 1.000000e-20 Hectoliter (hL).
| Attoliter (aL) | Hectoliter (hL) |

| 0.1 | 1.000000e-21 |
| 0.5 | 5.000000e-21 |
| 1 | 1.000000e-20 |
| 2 | 2.000000e-20 |
| 5 | 5.000000e-20 |
| 10 | 1.000000e-19 |
| 25 | 2.500000e-19 |
| 50 | 5.000000e-19 |
| 100 | 1.000000e-18 |

The attoliter is an extremely small unit of volume equal to 10⁻¹⁸ liters, or one quintillionth of a liter.
1 aL = 10⁻¹⁸ L = 10⁻²¹ m³ = 10⁻¹⁵ µL. One femtoliter = 1,000 aL.
To liters: multiply by 10⁻¹⁸. To femtoliters: divide by 1,000. To cubic nanometers: 1 aL = 10⁶ nm³.
Measuring individual molecular reaction volumes, nano-droplet volumes, and single-cell compartments.
A typical virus capsid can enclose a volume of just a few attoliters. The interior of a ribosome is measured in attoliters.
Confusing attoliters with femtoliters — there are 1,000 aL in 1 fL. The scale difference is enormous.
Prefix ladder: milli → micro → nano → pico → femto → atto. Each step is 10⁻³ smaller than the last.
The hectoliter is a metric unit of volume equal to 100 liters, commonly used in the beer and wine industries.
1 hL = 100 L = 0.1 m³ = 10 daL = 100,000 mL. One cubic meter = 10 hL.
To liters: multiply by 100. To gallons (US): multiply by 26.4172. To barrels (US beer): multiply by 0.8523.
Brewery production volumes, winery output, agricultural crop yields (grain in hL/hectare), and bulk liquid shipping.
Germany produces about 80 million hectoliters of beer annually. A standard US beer barrel equals about 1.17 hL.
Confusing hL with mL — they differ by a factor of 100,000. Always check prefix meanings carefully.
A hectoliter = 100 liters. Picture a large barrel or about 26 gallons. Breweries measure output in thousands of hectoliters.
