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) = 3.381402e-17 Fluid Ounce (US) (fl oz (US)).

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 US fluid ounce is a unit of liquid volume equal to 1/128 of a US gallon, or approximately 29.574 milliliters.
1 US fl oz = 2 US tbsp = 6 US tsp = 1/8 US cup = 29.5735 mL.
To mL: multiply by 29.5735. To UK fluid ounces: multiply by 1.04084. To tablespoons (US): multiply by 2.
Beverage cans (12 fl oz), water bottles (16.9 fl oz), coffee sizes, medicine dosing, and shampoo bottles.
A US fluid ounce of water weighs almost exactly 1 avoirdupois ounce (29.57 mL ≈ 28.35 g). The UK fl oz is slightly smaller (28.41 mL).
Confusing fluid ounces (volume) with ounces (weight). Also, US and UK fluid ounces differ slightly.
1 fl oz ≈ 30 mL (close enough). A soda can = 12 fl oz. A standard water bottle = 16.9 fl oz ≈ 500 mL.
