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) = 2.028841e+17 Teaspoon (US) (tsp (US)).

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 US teaspoon is a unit of culinary volume equal to 1/3 of a US tablespoon, or approximately 4.929 milliliters.
1 US tsp = 1/3 US tbsp = 1/6 US fl oz = 1/48 US cup ≈ 4.929 mL.
To mL: multiply by 4.929. To UK teaspoons: multiply by 0.832674. To tablespoons (US): divide by 3.
Cooking and baking recipes, measuring medicine doses, adding spices, sugar or salt, and child medication dosing.
The US teaspoon is slightly smaller than the metric teaspoon (5 mL). The phrase 'a teaspoon of sugar' equals about 4 grams.
Using a regular eating spoon instead of a measuring teaspoon — actual teaspoons vary widely. Always use a calibrated spoon.
3 tsp = 1 tbsp. 48 tsp = 1 cup. For mL conversion, remember 1 tsp ≈ 5 mL (the metric teaspoon is exactly 5 mL).
