Fixed point of a thermometer
WebA thermometer can be calibrated using the Fahrenheit scale in a similar manner as was described above. The difference is that the normal freezing point of water is designated as 32 degrees and the normal boiling point of water is designated as 212 degrees in the Fahrenheit scale.

Additional Information: To define a temperature scale in a thermometer, we need to choose two reference points, which are known as fixed points. In Celsius scale these fixed points are defined using properties of pure water.
WebThe polymath Isaac Newton (1643-1724) used linseed oil in his sealed-in-glass thermometers. His scale used three fixed-points: the temperature of air when water begins to freeze, the heat of blood in the human body and rapidly boiling water. On Newton's scale, freezing air was 0º, blood heat was 12º and boiling water was 34º.
