Six ounces equals 3/4 cup. One cup is equivalent to 8 ounces. Ounces measure only liquid ingredients in the United States. However, in the United Kingdom, ounces measure both dry and liquid ingredients. The conversion remains true regardless of the type of ingredient being used.
The simplest way to convert measurements while cooking is to use a conversion chart. This chart lists amounts, such as 6 ounces, next to the other measurement conversions, such as 3/4 cup, 12 tablespoons or 0.375 pound. A conversion chart can also convert U.S. measurements into metric units, such as 6 ounces equals 177 milliliters.
