Room temperature
Room temperature does not have an exact scientific definition. It means a temperature that is normal in rooms used by human beings.
Human comfort and health
changeA comfortable room temperature depends on individual needs and other factors. According to the West Midlands Public Health Observatory (UK), 21 °C (70 °F) is the recommended living room temperature, and 18 °C (64 °F) is a good bedroom temperature.[1]
However, in hotter countries such as those near the equator room temperature can be as high as 30 °C (86 °F).
Room Temperature is the temperature that is comfortable and normal to be in.
Science
changeFor scientific work, room temperature is taken to be in the range 20 to 25 °C (68–77 °F; 293–298 K; 528–537 °R) with an average of 23 °C (73 °F; 296 K; 533 °R). Scientists use kelvins (K) for temperature. The Rankine (°R) unit is no longer used.[2]
Condition for physical experiments
changeThe progress and results of many scientific and industrial processes can sometimes depend on the temperature of the surroundings of the equipment. For example, a measurement of the charge of the electron does not depend upon the temperature of the test equipment. In this case, if scientists mention temperature at all, they usually only mention "room temperature", which means that what is being measured has not been cooled or heated.
