Convert fluid ounces to US liquid quarts instantly. Ideal for cooking, canning, and container sizing.
Quick Answer: There are 32 fluid ounces in one US liquid quart. To convert oz to quarts, divide your fluid ounce value by 32. For example, 64 fl oz = 2 quarts, and 16 fl oz = 0.5 quarts.
Formula: quarts = fl oz ÷ 32
Quarts = Fluid Ounces ÷ 32
Fluid Ounces = Quarts × 32
One US liquid quart equals 32 fluid ounces. There are 4 quarts in a gallon (4 × 32 = 128 fl oz = 1 gallon), making quarts a convenient mid-point unit for liquid volume.
