Unit notes
This page uses the US customary fluid ounce. It is a volume ounce, not a weight ounce. A milliliter is one cubic centimeter and one thousandth of a liter.
Common mistakes
Do not mix US and Imperial units unless the page explicitly says so. If the query uses ounce, pint, quart, or gallon, check whether it means a liquid volume unit, a dry volume unit, or a mass unit. This page is locked to US fluid ounce -> milliliter.
When this page is the right answer
Use it when the source value is already in US fluid ounce and the target answer must be in milliliter. For a different pair, use full volume converter, US pint to liter, US quart to liter, cubic meters to US gallons, cubic yards to US gallons.
