To liters: multiply by 10⁹. To cubic meters: multiply by 10⁶. To megalliters: multiply by 1,000.
1 GL = 10⁹ L = 10⁶ m³ = 1,000 ML. One teraliter = 1,000 GL.
For example, 1 Gigaliter (GL) = 6110256.897 Barrel (UK) (bbl (UK)).

The gigaliter is a unit of volume equal to one billion liters (10⁹ L), or one million cubic meters.
1 GL = 10⁹ L = 10⁶ m³ = 1,000 ML. One teraliter = 1,000 GL.
To liters: multiply by 10⁹. To cubic meters: multiply by 10⁶. To megalliters: multiply by 1,000.
Reporting dam capacities (e.g., Hoover Dam stores ~35 GL), regional water budgets, and flood volumes.
Sydney Harbour holds approximately 500 GL of water. Lake Mead (behind Hoover Dam) has a capacity of about 35,200 GL.
Underestimating the scale — 1 GL = one billion liters = one million cubic meters. It is an enormous volume.
Think 'giga = billion.' 1 GL would fill 400 Olympic pools. It's the unit for dams and large reservoirs.
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.
