What Is the Difference Between Centigrade and Fahrenheit?

According to the Centigrade temperature scale, now known as Celsius, water freezes at zero degrees and boils at 100 degrees. According to the Farenheit scale, water freezes at 32 degrees and boils at 212 degrees.

To convert Celsius to Fahrenheit, multiply by nine, divide by five and add 32. To convert Fahrenheit to Celsius, subtract 32, multiply by five and divide by nine. Celsius is universally used in the sciences.

Andres Celsius and Daniel Gabriel Fahrenheit both developed temperature scales in the early 1700s. Soon after, Jean Pierre Cristin modified the boiling and freezing points in Celsius' scale and named it Centigrade. The name was changed to Celsius in 1948 as part of a global harmonization initiative. As of 2015, Celsius is the more common scale with the notable exception of the United States, which uses Fahrenheit.
