How to convert from Fahrenheit to Celsius
It is ease to convert a temperature value from Fahrenheit to Celsius by using the formula below:
[°C] = ([°F] − 32) × 5⁄9 
Value in Celsius = Value in × 9⁄5 + 32 
To change 0° Fahrenheit to Celsius, just need to replace the value [°C] in the formula below and then do the math.
Stepbystep Solution:
 Write down the formula: [°C] = ([°F] − 32) × 5⁄9
 Plug the value in the formula: (0  32) × 5⁄9
 Subtract 32: (32) × 5⁄9
 Multiply by 5: (160) × ⁄9
 Divide by 9: (17.777777777778)° = Value in Celsius (answer)
Using this converter you can get answers to questions like:

Definition of Fahrenheit
The F scale was invented by Fahrenheit, a German engineer, physicist and glass blower who also invented the mercury thermometer.
Fahrenheit is a temperature scale where the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point 212°F (at standard atmospheric pressure). This puts the boiling and freezing points of water exactly 180 degrees apart. The following formulas can be used to convert a temperature from Fahrenheit (°F) value to other temperature scales:
Fahrenheit to Celsius  [°C] = ([°F] − 32) × 5⁄9 
Fahrenheit to Delisle  [°De] = (212 − [°F]) × 5⁄6 
Fahrenheit to Kelvin  [K] = ([°F] + 459.67) × 5⁄9 
Fahrenheit to Newton  [°N] = ([°F] − 32) × 11⁄60 
Fahrenheit to Rankine  [°R] = [°F] + 459.67 
Fahrenheit to Reaumur  [°Ré] = ([°F] − 32) × 4⁄9 
Fahrenheit to Romer  [°Ro] = ([°F] − 32) × 7⁄24 + 7.5 
Definition of Celsius
The Celsius scale was invented in 1742 by the Swedish astronomer Anders Celsius. It was initially defined by the freezing point of water and later changed its definition as being the melting point of ice. 100° C was defined as the boiling point of water. The Celsius scale is a derived scale once its defined in relation to the Kelvin temperature scale. 0 (zero) °C is exactly equivalent to 273.15 K, with a temperature difference of 1 °C equivalent to a difference of 1 K, meaning the unit size in each scale is the same.
The Celsius temperature scale is sometimes referred to as the 'Centigrade' scale. Centigrade means divided into 100 degrees.
The following formulas can be used to convert a temperature from Celsius (°C) value to other temperature scales:
Celsius to Delisle  [°De] = (100 − [°C]) × 3⁄2 
Celsius to Fahrenheit  [°F] = [°C] × 9⁄5 + 32 
Celsius to Kelvin  [K] = [°C] + 273.15 
Celsius to Newton  [°N] = [°C] × 33⁄100 
Celsius to Rankine  [°R] = ([°C] + 273.15) × 9⁄5 
Celsius to Reaumur  [°Ré] = [°C] × 4⁄5 
Celsius to Romer  [°Ro] = [°C] × 21⁄40 + 7.5
