Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
Understanding the Units
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
What is a Fluid Ounce?
There are 8 fluid ounces in a US cup and 128 fluid ounces in a US gallon. The UK fluid ounce is slightly smaller (28.413 ml vs 29.574 ml), so UK and US recipes using fluid ounces will differ slightly.

Very close. Pure liquid densities are consistent across brands, so the ounces to fluid ounces conversion for water typically varies by less than 2-3%.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of water fills a different number of fluid ounces than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
