Most people think of a normal body temperature as an oral temperature of 98.6Â°F (37Â°C) . This is an average of normal body temperatures. Your temperature may actually be 1Â°F (0.6Â°C) or more above or below 98.6Â°F (37Â°C) .
The normal human body temperature is often stated as 36.5â37.5 Â°C (97.7â99.5 Â°F). In adults a review of the literature has found a wider range of 33.2â38.2 Â°C (91.8â100.8 Â°F) for normal temperatures, depending on the gender and location measured.n addition to varying throughout the day, normal body temperature may also differ as much as 0.5 Â°C (0.9 Â°F) from one day to the next, so that the highest or lowest temperatures on one day will not always exactly match the highest or lowest temperatures on the next day.
