Since the Fahrenheit and Celsius temperature scales were until recently both defined with respect to the freezing and boiling points of water at Standard Temperature and Pressure, the freezing point of pure water ought to be exactly 0° C or 32° F. At first, the Celsius scale was defined that way,

name Shannon status educator age 20s Question - The freezing point of water is 32 degrees Celsius. Is this the temperature at which water freezes, or does water freeze below 32 degrees? The reason I ask is that I am an editing a children's text book explaining the basics of weather.

Everybody knows 0 degrees on the Celsius scale is the freezing point of water and 100 degrees is the boiling point. On the Fahrenheit scale, however, freezing is 32 degrees and boiling 212.

0 degrees Celsius or 32 degrees Fahrenheit The freezing point of water is equal to 0 degrees Celsius. To convert from Celsius to Fahrenheit, multiply by 9, divide by 5, and add 32. In this instance, 0 x 9 = 0 / 5 = 0 + 32 = 32 degrees Fahre...

Pressure has an effect on the freezing point (or melting point) of water, though it isn't as substantial as the effect of pressure on boiling point. We could say that these values are at standard pressure, but realistically there is no noticeable difference of water's freezing point at various altitudes on earth.

Water freezes at 32o Fahrenheit (F) and boils at 212o F (at sea level, but 186.4° at 14,000 feet). In fact, water's freezing and boiling points are the baseline with which temperature is measured: 0o on the Celsius scale is water's freezing point, and 100o is water's boiling point.
