How Many Ounces in a Cup?
The number of ounces in a cup depends on what you're measuring — liquid (fluid ounces) or dry ingredients (weight ounces).
✅ Standard U.S. Measurement
🥛 For Liquids (Fluid Ounces):
1 cup = 8 fluid ounces (fl oz)
Examples:
-
1/2 cup = 4 fl oz
-
1/4 cup = 2 fl oz
-
3/4 cup = 6 fl oz
🌾 For Dry Ingredients (Weight Ounces):
Dry ingredients vary by weight, not volume. Example:
| Ingredient | 1 Cup (approx.) |
|---|---|
| All-purpose flour | 4.5 oz (128 g) |
| Sugar | 7 oz (200 g) |
| Butter (solid) | 8 oz (227 g) |
| Rice | 6.5–7 oz |
So:
1 cup = variable dry ounces (depends on the ingredient)
📏 Conversion Tip:
-
If you're using a recipe, always check whether it's measuring in fluid or dry ounces.
-
For best accuracy in baking, use a kitchen scale (especially for dry items).
