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) = 8.798770e-19 Quart (UK) (qt (UK)).

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 UK (imperial) quart is a unit of volume equal to 2 UK pints, or approximately 1,136.523 milliliters.
1 UK qt = 2 UK pt = 40 UK fl oz = 1/4 UK gallon ≈ 1,136.523 mL = 1.137 L.
To liters: multiply by 1.13652. To mL: multiply by 1,136.52. To US quarts: multiply by 1.201.
Older British recipes, some agricultural contexts, and historical trade measurements.
The UK quart (1,137 mL) is larger than a liter (1,000 mL), while the US quart (946 mL) is smaller than a liter.
Confusing UK and US quarts — they differ by about 20%. Always check which system a recipe or specification uses.
UK quart = 1.14 L (larger than a liter). US quart = 0.95 L (smaller than a liter). Easy way to remember the difference.
