Fluid Ounce (US) (fl oz)
The US fluid ounce, symbol fl oz, measures approximately 29.5735 milliliters. Its origins trace back to the British Imperial fluid ounce but were standardized differently in the United States. It is used for liquids in cooking, beverages, and nutrition. Fluid ounces bridge smaller units, such as teaspoons and tablespoons, with larger units, including cups, pints, and gallons, providing flexibility and precision in culinary measurements.
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.
