8 ounces is equivalent to 1 cup. To convert ounces to cups, you can use the following formula: 1 ounce = 0.125 cup. Therefore, 8 ounces multiplied by 0.125 equals 1 cup. It is important to note that this conversion is for liquid measurements. For dry ingredients, the conversion will depend on the ingredient itself, as different ingredients have different weights and densities.
