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) = 8.446816e+16 Dessertspoon (UK) (dsp (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 dessertspoon is a unit of volume equal to approximately 11.839 milliliters, or 2 UK teaspoons.
1 UK dsp ≈ 11.839 mL = 2 UK tsp ≈ 2/3 UK tbsp ≈ 0.417 UK fl oz.
To mL: multiply by 11.839. To UK teaspoons: multiply by 2. To US dessertspoons: multiply by 1.201.
British and Indian recipes, traditional herbal medicine dosing, and Commonwealth cooking instructions.
The dessertspoon was originally designed for eating dessert — positioned between the teaspoon and tablespoon in a formal place setting.
Assuming all dessertspoons are the same size — UK (~12 mL), Australian (10 mL), and US (~10 mL) versions differ.
A UK dessertspoon ≈ 12 mL, roughly double a UK teaspoon. In modern cooking, use a 10 mL metric spoon as a close substitute.
