Good to know
Weight ounces and fluid ounces are different
An ounce measures mass. A fluid ounce measures volume. Converting cups to weight ounces requires an ingredient density; converting cups to fluid ounces does not.
Keep the output set to ounces for a kitchen-scale result. Choose fluid ounces only when the recipe is asking for liquid volume.
Common questions
Questions, answered.
How many ounces are in a cup?
A US cup is 8 fluid ounces, but its weight in ounces depends on the ingredient. This page starts with all-purpose flour and calculates weight ounces.
Are ounces and fluid ounces the same?
No. Ounces measure weight, while fluid ounces measure volume.
Why do I need to choose an ingredient?
The ingredient density determines how much a cup weighs. Flour and sugar do not produce the same ounce result.
Can I reverse ounces to cups?
Yes. Use the swap button and keep the correct ingredient selected.
