Celsius - The Celsius scale is based on the freezing point of water set at 0 degrees and the boiling point set at 100 degrees. Celsius measurements are denoted by the letter C, and, similarly to Fahrenheit measurements, are incremented in degrees. However, it can be seen from the differing water boiling and freezing temperature ranges that the two measurement scales are not incremented equally. Where the Celsius scale has a range of 100 degrees between the boiling and freezing points of water, the Fahrenheit scale has a range of 180 degrees. This equates to a one degree Fahrenheit increment being equal to roughly a 0.56 degree Celsius increment. The two scales will only intersect at a common numerical temperature value at one point: -40 degrees. All other Celsius-to-Fahrenheit conversions will be accomplished by dividing the Celsius value by 0.56 and then adding 32.
