One of the most common questions home bakers ask is how many ounces in one cup butter, especially when a recipe calls for precise measurements and all they have on hand is a stick or a wrapper. Still, this conversion holds true primarily for solid, cold butter measured by volume. In the United States, butter is traditionally sold in sticks, with each stick typically equal to ½ cup. Practically speaking, this means one full cup of butter equals two sticks, and since each stick weighs 4 ounces (by weight), one cup of butter weighs 8 ounces. Understanding the distinction between volume and weight, and how different states of butter affect this relationship, is essential for consistent results in baking and cooking Not complicated — just consistent..
The Standard Conversion The most straightforward answer to how many ounces in one cup butter is 8 fluid ounces if measuring by volume, or 8 avoirdupois ounces if referring to weight. In practice, most recipes that call for "1 cup butter" expect the volume measurement, but professional bakers almost always prefer weighing butter using a kitchen scale. The reason is that butter's density can shift slightly depending on temperature, brand, and whether it's salted or unsalted. Day to day, a cup of cold, firm butter packed tightly will weigh slightly more than a cup of softened, loosely packed butter, even though the volume appears the same. Even so, this is why many experienced bakers keep a conversion chart handy: 1 cup = 16 tablespoons = 8 ounces by weight = 226. 8 grams.
