Teaspoon
The teaspoon (symbol tsp) is a traditional unit of volume used globally in culinary and pharmaceutical contexts. In the US customary system, a teaspoon equals 1/3 of a tablespoon or roughly 4.93 milliliters, whereas in modern metric practice it is standardized at exactly 5 milliliters (1/200 of a liter). The measure emerged in 17th-century England with the rise of tea culture before becoming a formal standard in cooking.
