To liters: multiply by 10¹⁵. To km³: multiply by 1,000. To teraliters: multiply by 1,000.
1 PL = 10¹⁵ L = 10¹² m³ = 1,000 km³ = 1,000 TL. One exaliter = 1,000 PL.
For example, 1 Petaliter (PL) = 3.519508e+15 Cup (UK) (cup (UK)).

The petaliter is a unit of volume equal to 10¹⁵ liters, or 1,000 cubic kilometers.
1 PL = 10¹⁵ L = 10¹² m³ = 1,000 km³ = 1,000 TL. One exaliter = 1,000 PL.
To liters: multiply by 10¹⁵. To km³: multiply by 1,000. To teraliters: multiply by 1,000.
No everyday practical use. Used for expressing very large natural water volumes in scientific literature.
All the world's rivers contain approximately 2.12 PL of water. Earth's ice caps hold about 26.5 PL of freshwater.
Rarely encountered, so the main mistake is not understanding the scale: 1 PL = one quadrillion liters.
Petaliters describe planet-scale volumes. Earth's total freshwater ≈ 35 PL. The prefix chain: kilo, mega, giga, tera, peta.
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.
