8ounce

8ounce is a term that can refer to an eight-ounce quantity in the United States customary system, and it is sometimes used as a stylized brand name or product label. It does not denote a single, universally defined entity, but rather appears in multiple contexts related to measurements and packaging.

In measurement terms, eight ounces can represent two different units depending on context. Eight avoirdupois ounces equal 226.796 grams, used for weight. Eight US fluid ounces equal 236.588 milliliters, used for volume. Because ounces for weight and for volume are not interchangeable, the actual amount of a substance by weight may differ from its volume, depending on density.

In consumer packaging, the eight-ounce size is a common standard for beverages, sauces, cosmetics, and other goods. Some brands adopt the term or a stylized form like “8ounce” to emphasize a compact, single-serving amount or a consistent packaging size. This usage is largely marketing-driven and varies by product category and market region.

Historically, the ounce originates from medieval weight systems and evolved through the avoirdupois and apothecaries systems. The eight-ounce figure is tied to practical serving sizes and recipe conventions in the United States, where many standards reference 8 fl oz as a cup.
