How Much Is 4 Ounces of Water in Cups?
4 ounces of water equals 0.48 cups. That's 113.40g, and Water has a density of 236.59g per cup. Because ounces measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 4 ounces of water
- Convert ounces to grams: 4 × 28.35 = 113.40g
- 1 cup of water = 236.59g
- 113.40g ÷ 236.59g/cup = 0.48 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
