  2. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    * 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.

  3. Human body temperature - Wikipedia

    en.wikipedia.org/wiki/Human_body_temperature

    This can be a normal body temperature for sleeping. 35 °C (95 °F) – Threshold for hypothermia. Intense shivering, numbness and bluish/grayness of the skin. There is the possibility of heart irritability. 34 °C (93.2 °F) – Severe shivering, loss of movement of fingers, blueness, and confusion. Some behavioral changes may take place.

  4. Skin temperature - Wikipedia

    en.wikipedia.org/wiki/Skin_temperature

    Anatomy of the human skin. 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.

  5. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = ⁠ f − 32 / 1.8 ⁠ c °C to f °F: f = c × 1.8 + 32

  6. Heat index - Wikipedia

    en.wikipedia.org/wiki/Heat_index

    For example, when the temperature is 32 °C (90 °F) with 70% relative humidity, the heat index is 41 °C (106 °F) (see table below). The heat index is meant to describe experienced temperatures in the shade, but it does not take into account heating from direct sunlight, physical activity or cooling from wind.

  8. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    Most scientists measure temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is the Celsius scale offset so that its null point is 0 K = −273.15 °C, or absolute zero. Many engineering fields in the US, notably high-tech and US federal specifications (civil and military), also use the Kelvin and ...

  9. Kelvin - Wikipedia

    en.wikipedia.org/wiki/Kelvin

    It was often called the "absolute Celsius" scale in the early 20th century. [6] The kelvin was formally added to the International System of Units in 1954, defining 273.16 K to be the triple point of water. The Celsius, Fahrenheit, and Rankine scales were redefined in terms of the Kelvin scale using this definition.
