Teaspoon (Metric): in the metric system, the teaspoon is not a standardized unit of volume. The metric system primarily uses the liter and its subunits, such as milliliters, for measuring volume. However, in culinary contexts, especially in recipes, people might refer to a "teaspoon" for convenience, as 1 metric teaspoon is often considered to be roughly equivalent to 5 milliliters.
