About teaspoons

The teaspoon (tsp) began as a spoon for stirring tea but became a critical unit of measure for potent ingredients like salt, baking powder, and spices. In the US, it is 1/6th of a fluid ounce (approx. 4.9 mL). The metric teaspoon is exactly 5 mL. This similarity means US and metric teaspoons are often interchangeable for home cooking without issues. teaspoons are commonly used in Spices and seasonings, Baking powder/soda, Vanilla extract, and Medicine (5 mL typically), Sugar in coffee.

A capful of vanilla extract is about 1 teaspoon.

About liters

The liter (L) is the metric system's unit for volume, defined as one cubic decimeter (10 cm x 10 cm x 10 cm). It was introduced in France in 1795 to standardize liquid measurement. Although technically a 'non-SI unit accepted for use with the SI,' it is the most common volume unit worldwide for beverages, fuel, and trade. It bridges the gap between small mL quantities and large cubic meter volumes. liters are commonly used in Soda and water bottles, Fuel tanks (outside US), Engine displacement (e.g., 2.0L engine), and Milk cartons (outside US), Scientific experiments.

A large water bottle is typically 1 liter.
