Methodology

How this ml to US fluid ounces converter works

This page converts milliliters into U.S. fluid ounces using the exact U.S. fluid-ounce definition as the underlying reference. It is useful for recipe scaling, product packaging, travel-size liquids, and any other case where a metric liquid amount needs to be expressed in U.S. fluid ounces.

Formula
US fluid ounces = milliliters ÷ 29.5735295625
milliliters The metric liquid volume you enter
29.5735295625 Exact milliliters in one U.S. fluid ounce
Example

250 mL ÷ 29.5735295625 = 8.45 U.S. fluid ounces.

A 330 mL soda can converts to 330 ÷ 29.5735 = 11.16 fl oz — close to the common 12 fl oz U.S. can size.

Assumptions
  • The conversion is based on U.S. fluid ounces.
  • The page converts liquid volume, not mass or ingredient weight.
  • Results are rounded for display only.
Notes
  • This is a common kitchen and packaging conversion.
  • Milliliters are metric volume units, while fluid ounces are U.S. customary volume units.
  • If you need cups instead, use the ml-to-cups page.

Milliliters to fluid ounces in practice

This conversion is the reverse of oz-to-mL and appears whenever metric packaging needs to be understood in U.S. terms. Wine bottles (750 mL ≈ 25.36 fl oz), soda cans (330 mL ≈ 11.16 fl oz), and pharmaceutical syrups (various mL sizes) are common examples. International recipes that list ingredients in milliliters can be quickly translated for cooks using U.S. fluid-ounce measuring cups. The factor 29.5735 mL per fluid ounce is based on the exact U.S. gallon definition.
