2. Heat index - Wikipedia

   en.wikipedia.org/wiki/Heat_index

   A given value of relative humidity causes larger increases in the heat index at higher temperatures. For example, at approximately 27 °C (81 °F), the heat index will agree with the actual temperature if the relative humidity is 45%, but at 43 °C (109 °F), any relative-humidity reading above 18% will make the heat index higher than 43 °C.

3. Apparent temperature - Wikipedia

   en.wikipedia.org/wiki/Apparent_temperature

   Dimension. Index calculated to be similar to a temperature. Apparent temperature, also known as " feels like ", [1][2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.

4. Room temperature - Wikipedia

   en.wikipedia.org/wiki/Room_temperature

   Retrieved 4 April 2018. 1.2.3.3 Definition of Room Temperature: According to the United States Pharmacopeia National Forumlary [sic] (USP-NF), the definition of room temperature is between 15 and 30 °C in the United States. However, in the EU, the room temperature is defined as being 15 to 25 °C, while in Japan, it is defined being 1 to 30 °C.

5. Mean radiant temperature - Wikipedia

   en.wikipedia.org/wiki/Mean_radiant_temperature

   Mean radiant temperature has been both qualitatively defined and quantitatively evaluated for both indoor and outdoor environments. [1] [2] [3] MRT has been defined as the uniform temperature of an imaginary enclosure in which the radiant heat transfer from the human body is equal to the radiant heat transfer in the actual non-uniform enclosure ...

6. Psychrometrics - Wikipedia

   en.wikipedia.org/wiki/Psychrometrics

   Determining the effect of temperature change on relative humidity: For air of a fixed water composition or moisture ratio, find the starting relative humidity from the intersection of the wet and dry bulb temperature lines. Using the conditions from the previous example, the relative humidity at a different dry bulb temperatures can be found ...

7. Dew point - Wikipedia

   en.wikipedia.org/wiki/Dew_point

   The dew point of a given body of air is the temperature to which it must be cooled to become saturated with water vapor. This temperature depends on the pressure and water content of the air. When the air is cooled below the dew point, its moisture capacity is reduced and airborne water vapor will condense to form liquid water known as dew. [1]

8. Thermal comfort - Wikipedia

   en.wikipedia.org/wiki/Thermal_comfort

   Thermal comfort is the condition of mind that expresses subjective satisfaction with the thermal environment. [1] The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate. The heat transfer is proportional to temperature ...

9. Wet-bulb globe temperature - Wikipedia

   en.wikipedia.org/wiki/Wet-bulb_globe_temperature

   Wet-bulb globe temperature. The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ...
