What is US Teaspoons?
US Teaspoons (US tsp) is a unit of volume. The US teaspoon is defined as exactly 4.92892 milliliters, or one-third of a US tablespoon. It is a volume unit used in US cooking measurements and nutritional labeling [nist-si-guide]. The US teaspoon is smaller than the metric teaspoon used in other countries. The US teaspoon evolved from traditional household measures and was standardized in the 19th century to align with US customary units. It was adopted for precise measurement in cooking and medicine [nist-si-guide]. US teaspoons are commonly used in the United States for recipes, dietary guidelines, and medicine dosing. Globally, the metric teaspoon of 5 milliliters is more common, but US teaspoons remain standard in US-based applications [nist-si-guide].
What is Milliliters?
Milliliters (mL) is a unit of volume. A milliliter (mL) is a unit of volume equal to one-thousandth of a liter, or exactly 1 cubic centimeter (cm³), as defined by the SI system. It measures liquid volumes in medicine, cooking, and science with high precision [bipm-si-brochure]. One milliliter corresponds to 0.001 liters or 10^-6 cubic meters. The liter was introduced in France in 1795 as part of the metric system, with the milliliter established as its subunit. The liter and its multiples were internationally standardized by the BIPM to harmonize measurement units [bipm-si-brochure]. Milliliters are used globally in healthcare for dosing liquids, in food and beverage industries for packaging, and in laboratory measurements. The unit is recognized by standards organizations such as ISO and NIST for scientific and commercial applications [nist-si-guide].
