When you recipe calls for ounces of some ingredient, it may be hard to measure. This is because most measuring spoons measure teaspoons and tablespoons, not fluid ounces. The same can be said for measuring cups. You can see lines on a measuring cup for 1/2 a cup or 1/4 a cup, but not ounces.
To convert 16 ounces to cups, you can simply use 2 cups as a substitute. To get the number of cups from fluid ounces, you divide the number of ounces by 8. So 16 ounces divided by 8 equals 2 cups. If you only have teaspoons, you multiply the number of ounces by 6. To convert 16 ouncesto teaspoons, this would equal 96 teaspoons.
