This change, however, raised the freezing point of water to 32 degrees, its present value and the answer to the first part of our problem. The boiling point, too, had to be changed.

A demonstration of freezing and boiling points, and standard measurements of temperature.

Celsius was set at 0 for the freezing/melting point of water and reaches 100 at the boiling point of water at sea level. For conversion, every degree of Celsius equals 1.8 degrees of Fahrenheit.
