Room temperature information


Mercury-in-glass thermometer measuring an ambient temperature of 23 °C (73 °F) a little above the room temperature range

Room temperature, colloquially, denotes the range of air temperatures most people find comfortable indoors while dressed in typical clothing. These temperatures feel comfortable to people wearing typical indoor clothing. But comfortable temperatures can be extended beyond this range depending on humidity, air circulation, and other factors.

In certain fields, like science and engineering, and within a particular context, room temperature can mean different agreed-upon ranges. In contrast, ambient temperature is the actual temperature, as measured by a thermometer, of the air (or other medium and surroundings) in any particular place. The ambient temperature (e.g. an unheated room in winter) may be very different from an ideal room temperature.

Food or beverages may be served at "room temperature", meaning neither heated nor cooled.
