In Fahrenheit scale, the freezing point of water is 32 degrees F (written: "32 °F"), and the boiling point is 212 degrees, placing the boiling and freezing points of water exactly 180 ° apart. On the Celsius scale, the freezing and boiling points of water are precisly 100 degrees apart, thus the unit of Fahrenheit scale, is 5/9 of a degree Celsius.
