To liters: multiply by 10¹². To cubic meters: multiply by 10⁹. To cubic miles: multiply by 0.23990.
1 km³ = 10⁹ m³ = 10¹² L = 10¹⁵ mL. One cubic mile ≈ 4.168 km³.
For example, 1 Cubic Kilometer (km³) = 3.519508e+12 Cup (UK) (cup (UK)).

The cubic kilometer is a unit of volume equal to a cube one kilometer on each side (10⁹ m³), used for extremely large volumes.
1 km³ = 10⁹ m³ = 10¹² L = 10¹⁵ mL. One cubic mile ≈ 4.168 km³.
To liters: multiply by 10¹². To cubic meters: multiply by 10⁹. To cubic miles: multiply by 0.23990.
Measuring lake volumes (Lake Baikal ≈ 23,615 km³), ice sheet volumes, and major reservoir capacities.
Earth's total ocean volume is about 1.335 billion km³. All human-made reservoirs combined hold only ~8,000 km³.
Underestimating the scale — 1 km³ = 10⁹ m³ = one trillion liters. It is a colossal volume.
Imagine a cube 1 km on each side — it would hold enough water to fill 400,000 Olympic swimming pools.
The UK (imperial) cup is a unit of volume equal to 10 UK fluid ounces, or approximately 284.131 milliliters.
1 UK cup = 10 UK fl oz = 1/2 UK pint = 284.131 mL ≈ 1.2 US cups.
To mL: multiply by 284.131. To US cups: multiply by 1.201. To liters: multiply by 0.284131.
Older British cookbooks, some Commonwealth recipes (especially pre-metric era), and traditional baking.
The UK cup is 20% larger than the US cup. A recipe calling for 1 UK cup actually requires about 1.2 US cups.
Using a US cup measure for a UK recipe — the 20% difference can ruin baked goods. Check the recipe's origin.
UK kitchens rarely use cups now — most British recipes specify grams and mL. If you see 'cups' in a UK recipe, it's 284 mL.
