Celsius

A commonly used scale to measure temperature of the intensity of heat is the Celsius scale. The Celsius scale is also commonly referred to as teh Centigrade scale. In degrees Celsius, water will boil at 100 degrees or 100C, which is the same temperature as 212F or 212 on the Fahrenheit scale. Water will freeze at 0 degrees Celsius or 0C, which is the same temperature as 32F or 32 on the Fahrenheit scale.

The temperature scale is usually shown after the number so that the number or temperature is not confused with other temperature scales, such as Celcius or Centigrade. These are also a very common temperature scales. When using these other scales, it is common to follow the number with a C. As an example, water boils at 100C.

Also understand you can convert tempeartures between the two scales, Celcius and Fahrenheit. To convert a temperature from Celcius to Fahrenheit, start by multiplying the Celcius temperature by 9. Divide that answer by 5 and then add 32. That will provide the temperature in degrees Fahrenheit.

As an example, start with 100C. Multiply by 9 equals 900. Divide 900 by 5 equals 180. Add 32 and your answer is 212 degrees Fahrenheit, which is the temperature water boils at. That is, 212F or 100C.
