Assuming we are dealing with a liquid ingredient, such as water or juice, we can convert 16.9 oz to cups as follows:
16.9 oz ÷ 8 oz/cup = 2.113 cups
So, 16.9 oz is equivalent to approximately 2.113 cups.
Common Ingredients and Their Densities
To provide a more comprehensive understanding of conversions, let’s examine the densities of some common ingredients:
| Ingredient | Density (g/ml) | 1 cup ≈ (oz) |
|---|---|---|
| Water | 1 | 8 |
| 0.5-0.6 | 4-4.5 | |
