The Fahrenheit scale is a commonly used temperature scale. In this scale, water freezes at 32 degrees and boils at 212 degrees. However, this only strictly holds when atmospheric pressure equals the average sea level pressure. At high altitudes, water boils at a lower temperature.
Another common scale is the centigrade (also called Celsius) scale. In this scale, water freezes at 0 degrees and boils at 100 degrees.
The conversion formulae are as follows:-
Fahrenheit = Centigrade x 1.8 + 32
Centigrade = Fahrenheit - 32 x 5/9
Insert a temperature in the appropriate box below - Fahrenheit or Centigrade (Celsius)
