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.
Teaspoon (Metric)
The metric teaspoon equals 5 milliliters, standardized to simplify cooking and medical measurements in countries that use the metric system. Unlike the US teaspoon, the metric teaspoon is slightly larger (5 mL vs ~4.92892 mL) and is widely used in recipes, pharmaceutical dosing, and nutrition labeling. Its simplicity ensures consistency across recipes and instructions internationally.
