Fahrenheit to Celsius

In this section, we will learn Fahrenheit to Celsius or °F to °C conversion, with example in detail. Before moving to the conversion, let's understand the definition of Fahrenheit and Celsius.


Fahrenheit is the unit to measure the temperature. It is represented by the symbol °F (read as degree Fahrenheit). The German physicist Daniel Gabriel Fahrenheit suggested the Fahrenheit scale. The Fahrenheit uses as an official temperature scale in the United States, the Bahamas, and other countries.


Celsius is also a unit to measure the temperature. It is also known as Centigrade. The symbol °C(read as degree Celsius or Centigrade) represents it.

Both Centigrade and Celsius are the naming conventions. There is no difference between Centigrade and Celsius. The Celsius invented by the Andes Celsius. It is also called Centigrade because the scale defined between 0 to 100 degrees. It is widely used in the scientific community. The Celsius scale is used worldwide.

In the following figure, the right scale represents the Fahrenheit scale and the left scale represents the Celsius scale.

Difference between Fahrenheit and Celsius

In the Fahrenheit scale, 32°F represents the melting point of the ice, while 212°F represents the boiling point of water. The absolute zero in the Fahrenheit scale is 459.67°C.

In the Celsius scale, 0°C represents the melting point of the ice, while 100°C represents the boiling point of water. The absolute zero in the Celsius scale is 273.15°C.

Fahrenheit to Celsius Conversion Formula

  • Subtract 32 from the given Fahrenheit temperature.
  • Multiply the resultant by 5/9 or divide the resultant by 8.

We can write the above steps in the formula terms as follows:

T°C = (T°F - 32) * 5/9


T°C = (T°F - 32) / (9/5)


T°C = (T°F - 32) / 1.8

Where T is the temperature that we want to convert.

We can also write the above formula as follows:

°C = (°F - 32) * (5/9)


°C = (°F - 32) / 1.8

Instead of °F, put the temperature which we want to convert.

The following table describes the typical temperature in Fahrenheit and Celsius.

Fahrenheit to Celsius

Let's see how to convert Fahrenheit to Celsius using the above formula.

Example 1: Convert 76°F to degree Celsius.


°C = (76 - 32) * (5/9)
°C = (44) * (5/9)
°C = 220 / 9
°C = 24.4444

The temperature 76°F is equal to 24.4444°C.

Example 2: Convert the room temperature into Celsius.


We know that the room temperature in Fahrenheit is 70°F.

°C = (70 - 32) / 1.8
°C = (38) / 1.8
°C = 21.1111

The room temperature 70°F is equal to 21°C.

Example 3: Convert the body temperature (Fahrenheit) into Celsius.


We know that the body temperature in Fahrenheit is 98.6°F.

°C = (98.6 - 32) / 1.8
°C = 66.6 / 1.8
°C = 37

The body temperature 98.6°F is equal to 37°C.

Example 4: Convert 16-degree Fahrenheit into Celsius.


°C = (16 - 32) / 1.8
°C = -16 / 1.8
°C = -8.88

16 °F is equal to -8.88°C.

Example 5: If the temperature of a city is 39°F, what will be the temperature of the city in Celsius?


°C = (39 - 32) / 1.8
°C = 7 / 1.8
°C = 3.89

The temperature of the city in Celsius is 3.89.
