Fahrenheit to Celsius (°F to °C) Converter
Use this unit converter to convert from Fahrenheit to Celsius or Celsius to Fahrenheit. Type your conversion into the input box. Temperature - C, Celsius, F, Fahrenheit.
You can use the formula C = 5/9(F - 32) to convert Fahrenheit to Celsius, and 9/5C = F - 32 to convert Celsius to Fahrenheit. These formulas are short versions of this equation: C/100=F-32/180.
As freezing point is within the range of 212 in the F thermometer, we have to subtract it, 32°F, from F temperatures ( F-32 ) and we also have to subtract it from 212, and that's how we get the 180 cipher.
