Melting ice (ice water) is used to find the 0° or 32° point. Boiling water is used to find the 100° or 212° point. The interval is then divided into 100 or 180 graduations. The bore of the thermometer is assumed to be of constant diameter.

A thermometer with a Celsius scale is divided into equal increments above and below 0, the temperature of ice water at sea level , and 100 degrees, the boiling point of water at sea level.
