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) = 0.000001 Picoliter (pL).

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 picoliter is a unit of volume equal to 10⁻¹² liters, or one trillionth of a liter.
1 pL = 10⁻¹² L = 10⁻⁹ mL = 1,000 fL = 10⁻⁶ µL. One nanoliter = 1,000 pL.
To liters: multiply by 10⁻¹². To nanoliters: divide by 1,000. To femtoliters: multiply by 1,000.
Inkjet printer droplet volumes (1–80 pL), PCR reaction miniaturization, and micro-array spotting.
A standard inkjet printer deposits droplets of 1–10 pL. Some advanced printers use 1.5 pL droplets for high-resolution photos.
Confusing pL with µL (microliter) — there are one million pL in a single µL.
Picoliter is the realm of inkjet drops and micro-fluidic reactions. 1 pL = a cube about 10 µm on a side — cell-sized.
