There are three temperature scales in common use today. The United States uses the Fahrenheit scale, nations that have adopted the metric scale use Celsius (sometimes called Centigrade), and the sciences use the Kelvin (or Absolute) scale.

All of these scales are related, and you can convert from one scale to another using temperature equations.

                5
     Celsius = --- * ( Fahrenheit - 32 )
                9


                   9
  Fahrenheit =  ( --- * Celsius ) + 32
                   5


      Kelvin = Celsius + 273
