Other organizations have established a variety of alternative definitions for their standard reference conditions. In chemistry, IUPAC has established two standards: standard temperature and pressure (STP) as a temperature of 273.15 K (0 Â°C, 32 Â°F) and an absolute pressure of exactly 100 kPa (1 bar).
The ideal core temperature is considered to be around 98.6Â° Degree Fahrenheit or 37Â° degree Celsius. This temperature is however, the average body temperature and the overall normal temperature varies from a minimum of 97.7Â° Fahrenheit (36.5Â° Celsius) to a maximum of almost 99.5Â° Fahrenheit (37.5Â° Celsius). Any temperature above or below this range is abnormal.
