A rectal temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

What is the normal rectal temperature for adults?
The normal body temperature for an adult is around 98.6°F (37°C) , but every person’s baseline body temperature is slightly different, and may consistently be a little higher or lower.
