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.
The cubic millimeter is a unit of volume equal to a cube with edges of one millimeter (10⁻⁹ m³), representing one billionth of a cubic meter.
1 mm³ = 10⁻⁹ m³ = 10⁻⁶ L = 1 µL = 0.001 cm³. One cubic centimeter contains 1,000 mm³.
To liters: multiply by 10⁻⁶. To cm³: divide by 1,000. To cubic inches: multiply by 6.1024 × 10⁻⁵.
Measuring tiny liquid drops, medical micro-dosing, ink droplet volumes in inkjet printers, and micro-fluidic devices.
A single raindrop contains roughly 50,000–100,000 mm³ of water. One mm³ of blood contains about 5 million red blood cells.
Confusing mm³ with mL — there are 1,000 mm³ in 1 mL. Also, forgetting that mm³ = µL in volume equivalence.
Remember: 1 mm³ = 1 microliter. Visualize it as a tiny cube only 1 mm on each side — barely visible to the naked eye.
