What is Celsius?

When various countries’ units for measurement are talked about, Celsius makes an important spot. Celsius is one of the scales considered for the measurement of temperature. It was first discovered or created by an astronomer going by the name of Anders Celsius. 

The Celsius scale starts with the melting point of pure water that is 0 degrees Celsius while it has the boiling point of water at 100 degrees Celsius. 

What is Fahrenheit?

When it comes to Fahrenheit it is also one of the commonly used units of temperature in the United States. It is mostly used when describing the weather. The Fahrenheit unit was given to us by a German physicist by the name of Daniel Gabriel Fahrenheit. 

The Fahrenheit scale shows the freezing point of water at 32 degrees Fahrenheit and the boiling point at 212 degrees Fahrenheit.

What is the relationship between Celsius and Fahrenheit?

The relationship between Celsius and Fahrenheit is described pretty well by the formula given below,

                          F= 9/5C +32

Therefore Fahrenheit finds its identity as 9 is to 5th parts Celsius added with 32. To understand the relationship between Celsius and Fahrenheit more in-depth

Conversion of 21-degree celsius in Fahrenheit

Following are the few steps that you can go through while converting 21 degrees celsius in Fahrenheit,

  • Step 1 

Mention the value provided and the value to be found. In this case, given is, Temperature in Celsius = 21°

To find, Fahrenheit =?

  • Step 2

The next step is to remind yourself of the relationship between Fahrenheit and Celsius. That is,

F= 9/5C +32

  • Step 3

This step includes putting the values in the formula at hand. 


F = 9/5 (21) + 32

  • Step 4

Finally, you can go ahead and solve the equation to find the value of Fahrenheit. 

F = 69.8

In this final step, we can conclude that 21-degree Celsius equals 69.8 degrees Fahrenheit.
