118C

118C is a designation that most commonly refers to the temperature value of 118 degrees Celsius. In the Celsius scale, 118°C equals 244.4°F or 391.15 K.

Because the boiling point of water at standard atmospheric pressure is 100°C, water at 118°C would be in vapor form unless pressure is increased to keep liquids, as would be the case in pressure vessels or industrial autoclaves. Therefore, 118°C is typically encountered as a setpoint in high-temperature processes such as sterilization, dehydration, or hydrothermal treatment conducted under pressure or with dry heat.

In practice, many industrial and laboratory processes specify temperatures close to, but not exactly, 118°C depending on material compatibility, time, and pressure. For example, sterilization protocols most commonly employ 121°C for steam sterilization, and other temperatures are chosen to balance efficacy and equipment constraints. The exact meaning of 118°C in a document depends on context and whether pressure is indicated alongside the temperature.

Beyond temperature, 118C can appear as an alphanumeric code, model number, or identifier in product catalogs, inventories, or route designations. In such cases, its meaning is not related to temperature and must be inferred from surrounding information.

In summary, 118C most often denotes a temperature of 118 degrees Celsius, with practical implications linked to pressure requirements when liquids are involved, and can also serve as a general code or label in various domains depending on context.
