Convert Fahrenheit to Celsius Formula and Method

Have you ever wondered why sometimes it is so hot that we prefer cooler drinks and wear shorts and t-shirts while sometimes it is so cold that we are wrapped in clothes from head to toe and are always drinking hot coffee or tea? Why does that happen? Well, the main reason is the change of seasons and because of that the temperature changes.

Cold and Hot

Temperature also changes as per the day’s duration. Like it is cooler at night and warmer during the day. We feel comfortable when the temperature is in our comfort range. The normal room temperature is 25 degrees Celsius, so when the temperature is around that range, we feel quite comfortable and outside that range always disturbs our inner peace.                  

Units of Temperature

There are five units of temperature overall. 

1. Celsius

2. Fahrenheit

3. Kelvin

4. Rankine

5. Reaumur

But the two most common units are Celcius and Fahrenheit. Next, we will learn how to convert Fahrenheit to Celsius.

How to Convert Fahrenheit to Celsius?

As we all know that one unit can be converted into other units by using a certain formula. Similarly, in order to convert a temperature given in Fahrenheit to a temperature in celsius, we use a certain formula.

Equation to Convert Fahrenheit to Celsius:

$F=\{C \times(\dfrac{9}{5})\}+32$

where

•  C = temperature in degrees Celsius

•  F = temperature in degrees Fahrenheit

We can also convert Celsius to Fahrenheit using the below formula:

$C=(F-32) \times \dfrac{5}{9}$

where

•  C = temperature in degrees Celsius

•  F = temperature in degrees Fahrenheit

The above is the Fahrenheit to Celsius formula.

Fahrenheit to Celsius Examples

Following are the Fahrenheit to Celsius examples.

Example 1. Convert 100 degrees Fahrenheit to Celsius.

Ans: Using the Fahrenheit to celsius formula, we get

$C=(F-32) \times \dfrac{5}{9}$

$C=(100-32) \times \dfrac{5}{9}$

$C=68 \times \dfrac{5}{9}$

$C=37.77 \text { degree celsius }$

Example 2.  Convert 48 degrees celsius to Fahrenheit.

Ans: We know the formula to convert Celcius to Fahrenheit is

$F=\{C \times(\dfrac{9}{5})\}+32$

$F=48 \times \dfrac{9}{5}+32$

$F=86.4+32$

$F=118.4 \text { degree Fahrenheit }$

Example 3. Convert 104 degrees Fahrenheit to Celsius.

Ans: Using the Fahrenheit to celsius equation, we get

$C=(F-32) \times \dfrac{5}{9}$

$C=(104-32) \times \dfrac{5}{9}$

$C=72 \times \dfrac{5}{9}$

$C=40 \text { degree celsius. }$

Summary

The temperature is extremely important for our day-to-day tasks to go on smoothly. If the temperature is extremely hot, then the daily task becomes difficult to carry out due to hot weather conditions. Similarly, if the temperature is too cold, day-to-day tasks become difficult too. The units of temperature also play major roles. The Standard International (SI) unit of temperature is Celsius. Similarly, other units like Fahrenheit, Kelvin, etc. are equally important.
