Look for fl oz on the label
Fluid ounces describe volume. Use this page for a bottle, carton or measuring jug marked fl oz. A label that gives oz by weight belongs to the ingredient-based ounces-to-cups converter.
Choose US or imperial fluid measures
The calculator starts with US fluid ounces and a US cup. Select a different supported standard when your recipe or measuring set specifies it. The selected units remain beside the result.
