What is Fahrenheit to Celsius conversion formula?
Celsius = (Fahrenheit - 32) ÷ 1.8 . To convert from degrees Fahrenheit to degrees Celsius, subtract 32 from the degree Fahrenheit and divide by 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 .

What is Fahrenheit?
Fahrenheit is a temperature scale with the freezing point of water is 32 degrees and the boiling point of water is 212 degrees under standard atmospheric pressure (101.325 kPa). The absolute zero temperature is -459.67 °F. The average body temperature in degrees Fahrenheit is generally accepted as 98.6 °F (between 97 °F and 99 °F). The Fahrenheit temperature scale is mostly used in the United States. It is named after German physicist Daniel Gabriel Fahrenheit (1724). The symbol for the Fahrenheit temperature scale is "°F".
What is Celsius?
Celsius (Centigrade) is a temperature scale with the freezing point of water is 0 degree and the boiling point of water is 100 degrees under standard atmospheric pressure (101.325 kPa). The absolute zero temperature is -273.15 °C. The average body temperature in degrees Celsius is generally accepted as 37 °C (between 36.1 °C and 37.2 °C). The Celsius temperature scale is a metric system derived SI temeperature unit and used in all countries except the United States. It is named after the Swedish astronomer Anders Celsius (1701–1744). The symbol for the Celsius temperature scale is "°C".
