Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 36.8 ± 0.5 °C (98.2 ± 0.9 °F). [12] This means that any oral temperature between 36.3 and 37.3 °C (97.3 and 99.1 °F) is likely to be normal. [13] The normal human body temperature is often stated as 36. ...
Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.

A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal ...
* Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.
300 years ago scientist Daniel Fahrenheit invented a temperature measurement — donning his last name. Once Fahrenheit came up with the blueprint for the modern thermometer, using mercury — he ...
The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit. [3] The symbol for degrees Rankine is °R [2] (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol. [4] [5]
New research finds the optimal room temperature range for sleeping for older adults. Here, experts explain the best temperature for sleep.
Temperature under the arm (axillary) is usually about 0.6 °C (1.1 °F) below core body temperature. [35] In adults, the normal range of oral temperatures in healthy individuals is 35.7–37.7 °C (96.3–99.9 °F) among men and 33.2–38.1 °C (91.8–100.6 °F) among women, while when taken rectally it is 36.7–37.5 °C (98.1–99.5 °F ...
