How to Convert Celsius to Fahrenheit
Converting Celsius to Fahrenheit is a straightforward process that can be done using a simple formula. Follow these steps to convert temperatures from Celsius to Fahrenheit:
 Take the Celsius temperature you want to convert.
 Multiply the Celsius temperature by 1.8. This accounts for the difference in scale between Celsius and Fahrenheit.
 Add 32 to the result. This adjusts the temperature to the Fahrenheit scale.
 The final value is the temperature in Fahrenheit.
For example, let’s convert 20 degrees Celsius to Fahrenheit:
20°C x 1.8 = 36
36 + 32 = 68°F
Therefore, 20 degrees Celsius is equal to 68 degrees Fahrenheit.
To help you visualize the conversion process, here’s a handy table:

Fahrenheit to Celsius Conversion Formula
To convert a temperature from Fahrenheit to Celsius, you can use the following formula:
°C = (°F – 32) x 5/9
This formula involves subtracting 32 from the Fahrenheit temperature and then multiplying the result by 5/9. By applying this conversion formula, you can easily and accurately convert temperatures from Fahrenheit to Celsius.
If you prefer, you can also use the alternate equation:
°C = (°F – 32) ÷ 1.8
Both formulas will yield the same result since dividing by 1.8 is equivalent to multiplying by 5/9. Whether you choose to subtract and multiply or subtract and divide, the outcome will be an accurate conversion from Fahrenheit to Celsius.
For visual reference, here is a table that showcases some common temperature conversions from Fahrenheit to Celsius:

Approximate Conversions
When it comes to temperature conversions, sometimes you just need a quick and rough approximation. Here’s a simple method you can use to get an estimated conversion from Celsius to Fahrenheit:

Double the Celsius temperature.

Add 30 to the doubled value.

The result is an approximate Fahrenheit temperature.
While this method may not provide the exact conversion, it can come in handy when you need a general idea of the Fahrenheit equivalent. Let’s see an example:
Example: We have a Celsius temperature of 25°C. Using the approximate conversion method:
Double the Celsius temperature: 25 x 2 = 50
Add 30 to the doubled value: 50 + 30 = 80
Therefore, an approximate Fahrenheit temperature for 25°C is 80°F.
