In this lesson, you will learn that ambient temperature can be interpreted in more than one way. You will also learn the range of temperatures that can be defined as ambient temperature in different situations.


Let's say that you live in Arizona. In the summer, it might be 110 degrees Fahrenheit (F) outside. However, I set the temperature of my home air conditioner at a cool 70 degrees F. Being a computer technician, you spend most of your time working on a computer inside a temperature-controlled server room at 68 degrees F. Which one is considered the ambient temperature? The definition of the word ambient is existing in or present in the surrounding area. Well, in a certain sense all three can be defined as the ambient temperature of the environment, my home, or a server room.

Ambient Weather Temperature

When talking about weather, the ambient temperature is the same as the current air temperature. Another way to say this is the ambient temperature is the same as the surrounding air temperature. Keep in mind that the humidity and wind may also change how the outside temperature 'feels', but they do not change the actual temperature reading. Depending on where you live you may experience how uncomfortable it can be when there is high humidity or even a strong wind chill.

In Air Conditioned Rooms

Since no one can control the surrounding air temperature outside, let's review a type of air temperature that can be controlled. You set your air conditioner at 70 degrees F. This would be considered the room temperature in your house. The typical definition of room temperature is the temperature at which most people are comfortable in a temperature-controlled environment. This varies from person to person, but it is somewhere between 68 and 77 degrees F on average. The temperature setting that is comfortable for an individual may fluctuate with humidity and outside temperature as well. The temperature of an air conditioned room can also be considered ambient temperature.
