The Celsius to Fahrenheit Formula and its Explanation

In order to convert a temperature from Celsius to Fahrenheit, you will learn how to use a formula in the coming paragraphs of this article. You'll also gain an understanding of the origin of this formula as well as how it was developed.

The following are the two subjects that are discussed in this article:

Celsius to Fahrenheit Formula

Use the following formula to convert a given temperature from Celsius to Fahrenheit:

Fahrenheit = (Celsius * 1.8) + 32

Let me convert a temperature of 37 degrees Celsius to its Fahrenheit equivalent.

F = (37 * 1.8) + 32
  = 66.6 + 32
  = 98.6

Therefore, 37 0C = 98.6 0F.

Now, let's move on to the explanation of the formula using the next section.

The explanation of the Celsius to Fahrenheit Conversion Formula

The following are the two scales that can be used to measure the temperature:

  • Degree Celsius (oC)
  • Degree Fahrenheit (oF)

The first is the Celsius scale, which is utilized by the vast majority of nations around the world. The second scale is the Fahrenheit scale, which is the one that is used in the United States. Both scales are utilized in the process of measuring temperature, which is something that is common knowledge to all of us.

Now that we understand how the formulas are created, let's move on to understanding how they convert into each other:

oC oF Purpose
100 212 Water boils (at normal pressure)
0 32 Water's freezing point

From the above table, we come to the point that:

  • Because the scale begins with two different numbers, 0 and 32 (the freezing point of water in degrees Celsius and Fahrenheit),
  • So 32 has to be added or subtracted.
    • to be added for converting Celsius to Fahrenheit
    • to be subtracted when converting from Fahrenheit to Celsius
  • And the temperature difference between boiling water and freezing water is 100-0 or 100 (for Celsius) and 212-32 or 180 (for Fahrenheit).
  • To convert from Celsius to Fahrenheit, multiply by 180/100 and then add 32.2
  • To convert Fahrenheit to Celsius, subtract 32 and then multiply by 100/180.

And as the value of 180/100 is 1.8, we have written 1.8 directly in the formula given at the beginning of this article.

To verify this formula, let's check it with the same value as given in the above table. Assume a temperature (in Celsius) is given; now we must convert it to Fahrenheit. So here is the formula:

F = (C * 1.8) + 32

Put the value of Celsius at 100 and calculate the Fahrenheit value as given below:

= (100*1.8)+32
= 180+32
= 212

So the value will be 212 in Fahrenheit.
