The temperature difference between the axillary temperature measurement and the ear temperature measurement is about 0.3°C. The temperature difference between the axillary temperature measurement and the ear temperature measurement is about 0.3°C. The standard value of body temperature is 36.0-37.3℃ for axillary temperature measurement and 36.3-37.5℃ for ear temperature measurement, while the standard value of body temperature is 36.3-37.5℃ for axillary temperature measurement. However, it is advocated to use mercury thermometer to measure the axillary temperature when available, which is relatively accurate, but for patients who cannot cooperate, or in cases where a quick reading is required, the ear measurement of body temperature can be used, but the measurement of body temperature through the ear can affect the true value of body temperature due to fluctuations in the external environment.
