Converting fluid ounce to milliliter comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using milliliter, or a laboratory protocol may specify volumes in fluid ounce that need to be measured with equipment calibrated in milliliter.
In everyday use, knowing that 5 fl oz = 147.9 mL and 10 fl oz = 295.7 mL covers most common situations. For bulk calculations, 100 fl oz = 2957 mL is a useful anchor. The reverse conversion — milliliter back to fluid ounce — uses the factor 0.03381, so 1 mL = 0.03381 fl oz.
All conversions use the internationally recognized factor of exactly 1 fl oz = 29.57 mL. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.
Formula: Milliliter = Fluid Ounce × 29.5735
Multiply any fluid ounce value by 29.5735 to get milliliter. One fluid ounce equals 29.5735 mL.
Reverse: Fluid Ounce = Milliliter × 0.033814057
Fluid ounces × 29.57 = mL. Round to × 30 for quick estimates.
One fl oz is about 30 mL — easy mental shortcut.
One cup (8 fl oz) = 236.6 mL ≈ 237 mL.
Labels product nutrition facts and serving sizes in fluid ounces as required by FDA.
Measures spirit pours and mixers in fl oz using jiggers for cocktail consistency.
Tracks soda fountain syrup and cup sizes (12, 16, 20, 32 fl oz) for inventory.
Designs bottle fill levels in fluid ounces for US retail compliance.
Recommends daily fluid intake for children in fluid ounces by age group.
Compares unit prices per fluid ounce on beverage labels to find the best value.
The US fluid ounce is defined as 1/128 of a US gallon, exactly 29.5735 mL. The US and UK fl oz differ: the US is 29.57 mL while the Imperial fl oz is 28.41 mL.
Fluid ounces appear on every US beverage container: a soda can is 12 fl oz, a water bottle is 16.9 fl oz, and a US shot glass is 1.5 fl oz.
Interesting fact: Despite sharing the name 'ounce', the fluid ounce measures volume, not weight. One fl oz of water weighs about 1.04 oz, but one fl oz of honey weighs about 1.5 oz.
The milliliter is one-thousandth of a liter, in use since the metric system was codified in France in 1795. The milli- prefix (from Latin mille, thousand) was standardized as part of the original SI prefix system.
Milliliters are the workhorse of medicine and cooking: syringes, dropper bottles, and nutritional labels all rely on mL for precise small-volume measurement. A standard US teaspoon is approximately 4.929 mL.
Interesting fact: The milliliter is numerically identical to the cubic centimeter (cm³), so 1 mL = 1 cm³ exactly. This equivalence is widely used in medicine, where a 5 cc syringe holds exactly 5 mL.
