How Do You Convert F to C Easily? Manual Process of Fahrenheit to Celsius Conversion

The conversion of degrees Fahrenheit to celsius can be calculated manually by using the temperature conversion formulas ie., Fahrenheit to celsius formula. As we know 0 degrees Fahrenheit is equal to -17.77778 degrees Celsius.

If you want to convert a Fahrenheit temperature to Celsius temperature to do any of our chemistry calculations then check out these following steps carefully:

  • Initiate with the temperature in Fahrenheit.
  • Now, subtract 32 from the given temperature and then divide the result by 1.8.
  • Simplify the expression and get the desired answer in degrees celsius temperature.

Look at the below-illustrated example on how to convert degrees F to C and grasp the manual process easily & quickly. Also, grab the opportunity to refer to the unit conversion calculator from and enhance your skills.


Convert 400° Fahrenheit to Celsius.


Given temperature in Fahrenheit is 400° F

Use the Fahrenheit to Celsius formula, °C = (°F - 32) / 1.8

Let's put the F value in the formula, we get

°C = (400 - 32) / 1.8 = 204.4°C

Hence, 204.4°C is the converted value from 400° Fahrenheit to Celsius.

Fahrenheit to Celsius Formula

The formula for converting temperatures from °F to °C is expressed as

°C = (°F - 32) × 5/9


°C = (°F - 32) / (9/5)


°C = (°F - 32) / 1.8


C = Measure of temperature in degree Celsius (°C).
F = Measure of temperature in degree Fahrenheit (°F).
