What exactly will you find in this article? You will know two formulas – first formula to turn Celsius into Fahrenheit use of which will give you an accurate result and second to know how to convert Celsius to Fahrenheit quickly. Of course, we will also show you how to use both of them in practice.

Celsius and Fahrenheit – some information

Before we move on to the formula to convert Celsius to Fahrenheit, we want to tell you a little about these two units.

As we said before, both Celsius and Fahrenheit are the units of temperature. What’s the difference between them?

The Celsius is the SI (International System of Units) derived unit. It is used mostly in continental Europe, for instance, in such countries like:

  • Germany,
  • Italy,
  • Russia.

The Fahrenheit is a part of the Imperial and US Customary systems of measurement. It is used mostly in the United States, but not only. You can meet with this unit also in, for instance, these countries:

  • Antigua and Barbuda,
  • the Bahamas,
  • Belize.

Have a look also at the relationship between the Celsius and Fahrenheit:

1 degree Celsius = 33.8 degrees Fahrenheit

1 degree Fahrenheit = -17.2222222 degrees Celsius

Thanks to this relationship the derivation of formula to convert Celsius to Fahrenheit was possible.

How do I convert from Celsius to Fahrenheit

We are going to show you the full formula to convert degrees Celsius to degrees Fahrenheit first. With its use you will be able to convert Celsius to Fahrenheit and get an accurate result. How to convert degree Celsius to Fahrenheit? Formula you can find down below.

We didn’t forget about a practical example too, so keep reading and learn how to use how to convert Celsius to Fahrenheit formula in practice!

Equation to convert Celsius to Fahrenheit

So, what is Celsius to Fahrenheit conversion formula? Have a look at the equation to convert Celsius into Fahrenheit down below:

(The Celsius degrees * 1.8) + 32 = The Fahrenheit degrees

As you can see, it is a mathematical formula for converting Celsius to Fahrenheit. If it looks too complicated for you, have a look at step by step explanation:

°C * 1.8 = X

X + 32 = °F

We hope it is clearer now. So, if you know how the formula to convert C to Fahrenheit looks, it is time to learn how to use it.

As you can see, you need to do 2 mathematical operations to get the result. First, multiplying, and second, adding. To be more precise, you need to:

  1. Multiply the Celsius degrees by 1.8.
  2. Add 32 to the result from the first point.

And then you will get the result in Fahrenheit degrees.

Let’s see it on the example now.

How to convert Celsius to Fahrenheit formula

So how to convert Celsius to Fahrenheit? Formula is given above, so we can move on to practice. To learn how to convert Celsius to Fahrenheit formula example is the best way. Why? Thanks to a practical example the formula to convert Celsius to Fahrenheit in C will be easier to remember for you.

How to convert Celsius to Fahrenheit in c with the formula? Here is the example. For instance, calculate 20 Celsius degrees to Fahrenheit. The equation to convert Celsius into Fahrenheit in this case will look like this:

(20 °C * 1.8) + 32 = 68 °F

To make it clearer, we will also show this example step by step. It is down below. Have a look:

20 °C * 1.8 = 36

36 + 32 = 68 °F

Easy formula for converting Celsius to Fahrenheit in practice

Now it is time for the “how to” part of the topic of the easy formula for converting Celsius to Fahrenheit. How to convert Celsius to Fahrenheit with the easier formula? Have a look.

How to – Celsius to Fahrenheit conversion formula in an easier form in practice:

For instance, calculate 20 °C like in the case of the full formula. Thanks to this we will be able to compare these two results and show you the difference between them. The equation to convert Celsius to Fahrenheit will be look like this:

(20 °C * 2) + 30 = 70 °F

It is also possible to write this equation step by step, as in the case of the full formula. Have a look:

20 °C * 2 = 40

40 + 30 = 70 °F

As you can see, the result is 70 °F now. Then, it was 68 °F. So the difference is only 2 °F. If you do not need an exact result, using this easy formula for converting Celsius to Fahrenheit will be a quicker and easier way to convert Celsius to Fahrenheit than using the full formula instead.
