Note: US cups are typically used as a kitchen measurement for both liquid ingredients and dry ingredients. Conversely, ounces are a weight measurement while fluid ounces are a volume measurement. To make things more confusing, although most recipes use cups for liquid measurements, most commercial products use fluid ounces.

U.S. to Metric

One important thing to note with these cooking measurement conversions is that they directly translate imperial measurements to their metric counterparts. But, it's common in recipes using the metric system to use weight measurements for dry ingredients instead of volumetric ones. If you don't have a kitchen scale handy, you might have to be a bit clever with your measuring cups.

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 1 ounce to cups, you can simply use 1/8 cup as a substitute. To get the number of cups from fluid ounces, you divide the number of ounces by 8. So 1 ounce divided by 8 equals 1/8 cup. If you only have teaspoons, you multiply the number of ounces by 6. To convert 1 ounce to teaspoons, this would equal 6 teaspoons.
