Teaspoon (US) (tsp)
The US teaspoon is a customary cooking unit equal to approximately 4.92892 milliliters. Its origin comes from traditional household spoons used for measuring spices and small quantities of liquid. The teaspoon has become a standard unit in American recipes, baking, and mixology, allowing for repeatable and accurate measurements. While small, it plays a critical role in precise culinary measurements and is often paired with tablespoons, cups, and other US volume units in recipes.
Milliliter (mL)
The milliliter, symbol mL, is a metric unit of volume equal to one-thousandth of a liter. Introduced alongside the metric system in the late 18th century in France, it provides a practical measure for small liquid quantities, such as in cooking, pharmaceuticals, and laboratory work. One milliliter of water is approximately equal to one cubic centimeter, making conversions between mass and volume straightforward for water-based liquids. The milliliter’s adoption worldwide has standardized recipes, measurements, and scientific experiments, allowing for precision and consistency across countries.
