Historically, on the Fahrenheit scale the freezing point of water was 32 °F, and the boiling point was 212 °F (at standard atmospheric pressure). This put the boiling and freezing points of water 180 degrees apart. [8] Therefore, a degree on the Fahrenheit scale was 1 ⁄ 180 of the interval between the freezing point and the boiling point ...
Scale of temperature is a methodology of calibrating the physical quantity temperature in metrology.Empirical scales measure temperature in relation to convenient and stable parameters or reference points, such as the freezing and boiling point of water.
In the United States, the Fahrenheit scale is the most widely used. On this scale the freezing point of water corresponds to 32 °F and the boiling point to 212 °F. The Rankine scale, still used in fields of chemical engineering in the US, is an absolute scale based on the Fahrenheit increment.

In the case of the Celsius scale (and the long since defunct Newton scale and Réaumur scale) the melting point of ice served as such a starting point, with Celsius being defined (from the 1740s to the 1940s) by calibrating a thermometer such that: Water's freezing point is 0 °C. Water's boiling point is 100 °C.
