As a liquid, 4 fl oz is the 1/2 cup measure, or 8 tablespoons. That is the volume of a small juice glass, roughly 118 mL.
Labels with "4 oz" on them are usually weight. Many baby food jars are labeled around 4 oz by weight; smooth purée is close to water in density, so the jar holds about 1/2 cup. A stick of butter is 4 oz by weight and also 1/2 cup, another case where both numbers line up.
Now the trap: 4 oz of shredded cheese is about 1 cup, because loose shreds are mostly air. And 4 oz of flour is close to 1 cup as well. When a recipe lists ounces for a dry ingredient, check dry vs. liquid ounces before reaching for the 1/2 cup.
