About Milliliters
A milliliter (mL) is one thousandth of a liter (0.001 L) and exactly equal to one cubic centimeter (cc/cm³). It is one of the most commonly used units in everyday life - standard medicine doses, cooking measurements, and beverage labels all reference milliliters. A standard teaspoon holds about 5 mL, a tablespoon 15 mL, and a standard wine glass typically 150-250 mL. The milliliter is the workhorse of liquid measurement in medicine, cooking, chemistry, and consumer products worldwide, bridging the gap between the full liter and laboratory-scale measurements.
About Teaspoons
A teaspoon (tsp) is a US customary and cooking measurement unit equal to 1/3 of a tablespoon - approximately 4.929 mL. It is fundamental to cooking and baking worldwide: nearly every recipe in US-published cookbooks uses teaspoons as the basic small measurement for spices, baking powder, vanilla, and other minor ingredients. In medicine, over-the-counter liquid medications (especially children's doses) are measured in teaspoons, with 5 mL the standard metric equivalent used on US medication labels. Three teaspoons make one tablespoon, and six teaspoons make one fluid ounce.
