Why Convert US Fluid Ounces to Milliliters?
Converting between us fluid ounces (fl oz (US)) and milliliters (mL) is one of the most common volume conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert fl oz (US) to mL saves time and prevents errors.
Volume conversions (fl oz (US) to mL) play a key role in the automotive industry, cooking, and chemical manufacturing. Drivers comparing engine displacement or fuel tank capacity need clear conversions to understand vehicle performance and range. In the kitchen, converting liquid ingredients like milk, oil, or broth is essential when adapting recipes from different regions. For industrial applications, mixing chemical solutions requires exact volume measurements to maintain product stability and safety. An error in volume conversion can lead to mechanical failures, ruined culinary creations, or hazardous chemical reactions, making precision indispensable.
How to Convert US Fluid Ounces to Milliliters
To convert us fluid ounces to milliliters, use the following formula:
mL = fl oz (US) × 29.57352956
Example: 1 fl oz (US) = 29.57352956 mL
For example, 5 fl oz (US) = 147.8676478 mL, 10 fl oz (US) = 295.7352956 mL, and 100 fl oz (US) = 2957.352956 mL. For larger values, 1000 fl oz (US) = 29573.52956 mL. Conversely, 1 mL = 0.0338140227 fl oz (US). Our calculator above performs this conversion instantly with full precision — no rounding errors.
Common Use Cases
- Standard US soda can (12 fl oz): 12 fl oz (US) = 354.8823547 mL
- US pint glass of beer: 16 fl oz (US) = 473.176473 mL
- Standard glass of water (8 fl oz): 8 fl oz (US) = 236.5882365 mL
- Shot of espresso (≈1 fl oz): 1 fl oz (US) = 29.57352956 mL
Common Mistakes to Avoid
- Fluid vs Dry: confusing fluid pints/quarts with dry pints/quarts.
- US vs Imperial: US gallons are smaller than UK Imperial gallons.
- Cubic conversion: forgetting to cube linear factors (1 m = 100 cm, 1 m³ = 1,000,000 cm³).
Pro Tips
- Cooking spoon: 1 Tablespoon = 3 Teaspoons = 15 ml.
- Cup size: A standard US cup is 240ml, but metric cup is often 250ml.
- Cube visual: 1 cubic meter is a box 1m x 1m x 1m (huge!).
What is a US Fluid Ounce?
The US fluid ounce (fl oz) is a unit of volume. It is equal to 1/128 of a US gallon, or approximately 29.57 milliliters.
Fluid ounces are widely used in the US for beverage labeling (soda, beer), medicine dosages, and liquid products.
What is a Milliliter?
The milliliter (mL) is a metric unit of volume equal to one-thousandth of a liter. One milliliter occupies the same volume as one cubic centimeter.
Milliliters are used globally for measuring small amounts of liquid, dosages of medicine, beverage packaging, and cooking ingredients.
