Convert US fluid ounces (fl oz) to milliliters (mL)
Fluid Ounce (US)
Definition: The US fluid ounce (symbol: fl oz) is a unit of volume used for measuring liquids. One US fluid ounce equals exactly 29.5735 milliliters. There are 2 tablespoons in 1 fluid ounce, 8 fluid ounces in 1 cup, and 128 fluid ounces in 1 gallon. Important: Fluid ounces measure volume, not weight. They are different from ounces (oz) which measure weight.
History/origin: The fluid ounce was originally based on the volume occupied by one ounce of water. The US fluid ounce was standardized in 1959 as exactly 29.5735 milliliters, which is approximately 4% smaller than the imperial fluid ounce used in the UK.
Current use: The US fluid ounce is commonly used in the United States for measuring beverages, cooking ingredients, medicine dosages, and nutrition labels. It's the standard unit on US food packaging and recipes. Soft drinks, juice boxes, water bottles, and many beverages display their volume in fluid ounces. Converting fluid ounces to milliliters is essential for international recipe conversions and scientific measurements.
Milliliter
Definition: The milliliter (symbol: mL or ml) is a metric unit of volume equal to one-thousandth of a liter. One milliliter equals exactly one cubic centimeter (1 cm³). The milliliter is part of the International System of Units (SI) and is the standard unit for measuring small liquid volumes worldwide.
History/origin: The milliliter was derived from the liter, which was first defined in 1795 during the French Revolution. The prefix "milli-" means one-thousandth, so one milliliter is 0.001 liters. The milliliter is convenient for measuring small to medium quantities and is widely used in medicine, chemistry, and cooking.
Current use: The milliliter is used worldwide for measuring small to medium volumes in cooking, medicine, chemistry, and everyday life. It's the standard unit for liquid medications, beverage servings, cooking ingredients, and laboratory measurements. Converting US fluid ounces to milliliters is essential for international recipes and metric measurements.
