To liters: multiply by 10⁻¹². To nanoliters: divide by 1,000. To femtoliters: multiply by 1,000.
1 pL = 10⁻¹² L = 10⁻⁹ mL = 1,000 fL = 10⁻⁶ µL. One nanoliter = 1,000 pL.
For example, 1 Picoliter (pL) = 6.110257e-15 Barrel (UK) (bbl (UK)).

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.
The UK (imperial) barrel is a unit of volume equal to 36 imperial gallons, or approximately 163.659 liters.
1 UK barrel = 36 UK gal = 288 UK pt = 5,760 UK fl oz ≈ 163.659 L ≈ 1.637 hL.
To liters: multiply by 163.659. To UK gallons: multiply by 36. To US barrels: multiply by 1.373.
Historical UK brewing trade, legacy contracts and legal references, and traditional measurements in some industries.
The UK barrel (36 imp gal ≈ 164 L) is different from both the US liquid barrel (31.5 US gal ≈ 119 L) and the oil barrel (42 US gal ≈ 159 L).
Confusing UK, US, and oil barrels — they are all different sizes. Always specify the barrel type.
A UK barrel = 36 imperial gallons ≈ 164 liters. Remember: there are at least 3 common barrel sizes — UK, US, and oil.
