The US barrel is a unit of volume equal to 31.5 US gallons (about 119.24 liters), used for various liquid commodities.
1 US barrel = 31.5 US gal = 119.24 L = 0.11924 m³ = 4,032 US fl oz.
To liters: multiply by 119.24. To US gallons: multiply by 31.5. To UK barrels: multiply by 0.729.
Brewery production volumes, whiskey barrel aging, wine production, and bulk liquid commodity trading.
A bourbon whiskey barrel is 53 gallons (200 L), larger than the standard US liquid barrel. Barrel sizes vary by commodity and country.
Confusing the US liquid barrel (31.5 gal) with the petroleum barrel (42 gal). Always specify which barrel type.
There are several different 'barrel' sizes. US liquid = 31.5 gal, US oil = 42 gal, UK = 36 imperial gal. Always specify!
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.
