How to position the eyes correctly when determining the temperature?

Almost every inhabitant of the planet, especially in the cold season, looks at the thermometer before going outside. But not everyone is doing it right. The main error in measuring temperature is due to the fact that a person does not look at a right angle, but from above or below. Thus, the readings of the device are distorted and seem to be either less or more, respectively. In order to correctly determine the temperature of the thermometer, it is necessary to position your eyes strictly at the same level as the liquid column in the tube. Only then will your testimony be correct.
