37C

37°C denotes thirty-seven degrees Celsius, a unit of temperature on the Celsius scale. It is equivalent to 98.6°F (approximately, since conversion is (°C × 9/5) + 32). On medical and scientific notes, 37°C is commonly cited as the typical or normal core body temperature for humans, though individual values vary and measurement method matters.

In physiological terms, the body maintains core temperature through hypothalamic thermoregulation. Normal ranges typically span about 36.1 to 37.2°C, with temperatures rising slightly in the afternoon or after physical activity. A fever is generally recognized as a body temperature at or above around 38°C, signaling an immune response to infection or illness. Hypothermia occurs when core temperature falls below about 35°C.

In laboratory contexts, 37°C is a standard incubation temperature for many mammalian cell cultures and several microorganisms. Incubators at this temperature support cellular processes and growth, though some cell types or species require different incubation conditions, such as variations in humidity or carbon dioxide levels.

For measurement, temperatures can be recorded orally, rectally, or via other sites, each with its own typical bias relative to core body temperature. The Celsius scale and its relation to Fahrenheit are commonly used in science and medicine, with the familiar conversion formulas aiding quick translation between scales.

Overall, 37°C serves as a practical reference point in human physiology and biomedical research, reflecting a conventional target for normal body temperature and standard lab practices.
