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.
