The Conversion Formulas
If you prefer to perform the math manually or are writing your own conversion script, the relationship between mL and US fl oz is internationally standardized. One US Fluid Ounce is equal to exactly 29.5735295625 milliliters. For general use, this is rounded to 29.5735. The standard formulas are:
- Milliliters to Fluid Ounces Formula:
fl oz = mL ÷ 29.5735(or multiply by ~0.033814) - Fluid Ounces to Milliliters Formula:
mL = fl oz × 29.5735
Example Calculation (Converting 500 mL of water):
If a recipe calls for 500 mL of water and you only have measuring cups marked in fluid ounces, divide 500 by 29.5735. The resulting accurate answer is roughly 16.907 fl oz.

Frequently Asked Questions
Is a fluid ounce the exact same as a regular ounce?
No. A fluid ounce (fl oz) is a unit of volume used to measure liquids like water, milk, or oil. A regular ounce (oz) is a unit of mass or weight used for dry ingredients like flour, sugar, or mail parcels. They are measured differently and cannot be used interchangeably without knowing the density of the ingredient.
What is the difference between US and UK Imperial Fluid Ounces?
A US fluid ounce is slightly larger, equal to exactly 29.5735 mL. The UK Imperial fluid ounce is slightly smaller, equaling 28.4131 mL. This calculator specifically utilizes the standard US fluid ounce, which is standard across most modern digital recipe sites.
How many milliliters are in an 8-ounce glass of water?
An 8 fluid ounce glass of water is equal to approximately 236.59 milliliters. This is also the exact mathematical equivalent of one standard US culinary measuring cup.
