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) .
Normal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 7002309950000000000â 36.8Â±0.5 Â°C (7002309927777777777â 98.2Â±0.9 Â°F). This means that any oral temperature between 36.3 and 37.3 Â°C (97.3 and 99.1 Â°F) is likely to be normal.
