What is Fahrenheit to Celsius conversion formula?
Celsius = (Fahrenheit - 32) ÷ 1.8
The 1.8 Celsius to Fahrenheit ratio means there are 1.8 Fahrenheit degrees for each Celsius degree and it is calculated by dividing the difference between boiling and freezing points for each of these temperature scales, that makes (212 °F - 32 °F) / (100 °C - 0 °C) = 1.8 .
The 32 is the difference between freezing point of Fahrenheit (32) and freezing point of Celsius (0).
How to convert from Fahrenheit to Celsius?
To convert from Fahrenheit to Celsius degrees, fist subtract 32, then divide the result by 1.8 ratio.
For example, to convert from 77 °F to °C, subtract 32 from Fahrenheit first and then divide by 1.8, that makes (77 °F - 32) / 1.8 = 25 °C .
