28C

28C is an alphanumeric label that can denote different things depending on context. The combination of the number 28 and the letter C appears in several domains, including temperature notation, clothing sizing, and electronics part numbers. Because it is not unique, clarification is usually required to determine the intended meaning.

In temperature notation, 28°C means twenty-eight degrees Celsius, which is 82.4°F. This value is commonly used to describe environmental conditions, food storage guidelines, or laboratory and clinical settings.

In clothing and lingerie, 28C can indicate a bra size, with 28 representing the band size and C the cup size. Availability and sizing conventions vary by brand and region, so measurements and fit guidelines are typically product- or manufacturer-specific.

In electronics and manufacturing, 28C may appear as part of a model or part number, such as in memory devices or other components. The exact meaning is defined by the manufacturer and is usually documented in product datasheets or catalogs. The same label can refer to different items across brands, so cross-checking the full part number is important.

Other uses may include route designations, catalog codes, or internal indexing schemes within organizations or systems. In each case, 28C is a shorthand that requires accompanying context—such as a product line, region, or specification—to be interpreted correctly.
