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) = 5.631201e+16 Tablespoon (UK) (tbsp (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 tablespoon is a unit of culinary volume equal to approximately 17.758 milliliters, or 3 UK teaspoons.
1 UK tbsp ≈ 17.758 mL = 3 UK tsp. About 20% larger than a US tablespoon (14.787 mL).
To mL: multiply by 17.758. To US tablespoons: multiply by 1.201. To metric tablespoons: multiply by 1.184.
Traditional British baking and cooking, Commonwealth recipes, and older pharmaceutical references.
Australia officially uses a 20 mL tablespoon, the UK uses ~17.8 mL, and the US uses ~14.8 mL — three different sizes for the same name!
Mixing up UK and US tablespoons in international recipes. A UK tbsp is ~20% larger than a US tbsp.
Modern UK cooking is shifting to metric (15 mL). When following old UK recipes, add ~20% more than a US tbsp would indicate.
