Volume unit conversion guide
Convert liquid and bulk volume measurements for cooking, fuel economy discussions, chemistry homework, and product labels. Supported units include milliliters, liters, US gallons, UK gallons, US fluid ounces, and US cups.
US and UK gallons are not the same: a US gallon is smaller than an imperial (UK) gallon. US fluid ounces and cups are standard in American recipes. Most other countries label beverages and ingredients in milliliters and liters.
When you import a recipe or compare container sizes internationally, mismatched volume units are a common source of error. Enter the value exactly as printed on your source, then switch to the unit required by your destination recipe or regulation.
Use the table view to see how one volume compares across all supported units. For privacy, cookies, and advertising choices on unitivo.org, open the Privacy policy from the site footer.
