32 oz to cups
If you mean fluid ounces (liquid volume), 32 fl oz = 4 cups. If you mean weight ounces of a dry ingredient, the answer depends on density — 32 oz of flour is about 7 9/16 cups. Both are below.
4 cups (fluid)
32 fluid ounces ÷ 8 fl oz per cup = 4 cups
Fluid ounces vs weight ounces
This is the trap with “oz to cups.” A fluid ounce is a unit of volume; a regular ounce is a unit of weight. They only line up for water. For dry goods you must use the ingredient's density, which is why the weight table below differs for each one.

Frequently asked questions
How many cups is 32 oz?
For liquids measured in fluid ounces, 32 fl oz equals 4 cups, since there are 8 fluid ounces in a US cup. For dry ingredients measured by weight, it depends on density — 32 oz of flour is about 7 9/16 cups.
Is 32 oz fluid ounces or weight ounces?
Recipes can mean either. Fluid ounces measure volume (8 fl oz = 1 cup). Weight ounces measure mass and must be converted using the ingredient's density. Check whether your recipe lists "fl oz" (volume) or "oz" by weight.
How many cups is 32 fluid ounces of water?
Water is the reference liquid, so 32 fluid ounces of water is 4 cups exactly.
