Celsius vs Fahrenheit vs Kelvin: Temperature Scale Comparison

If you’ve ever visited another country, you’ve probably encountered various temperature scales. Although you might be accustomed to seeing temperatures in Celsius, temperatures are sometimes given in Fahrenheit in other countries. Perhaps you are familiar with the Kelvin scale but are unsure of how it differs from the other two. So lets discover the differences between Celsius vs Fahrenheit vs Kelvin .

What are Celsius, Fahrenheit, and Kelvin?

Let’s first define the three temperature scales before delving into their differences.


The Celsius scale, also known as the centigrade scale, which measures temperature, is based on the freezing and boiling points of water. On this scale, water has a boiling point of 100 °C and a freezing point of 0 °C at normal atmospheric pressure.


The Fahrenheit scale, which measures temperature, was created in 1724 by German physicist Daniel Gabriel Fahrenheit. At standard atmospheric pressure, water has a boiling point of 212 degrees Fahrenheit (°F) and a freezing point of 32 degrees Fahrenheit (°F) on this scale.


The Kelvin scale, also called the absolute temperature scale, is based on absolute zero, the chillyest possible condition. Absolute zero on this scale is represented by 0 Kelvin (K), and one Kelvin is equal to one degree Celsius.

How to Convert Between Kelvin, Celsius, and Fahrenheit

Anyone who needs to work with temperature data must understand how to convert between the various temperature scales. The conversion formulas between Celsius, Fahrenheit, and Kelvin are as follows:

Celsius to Fahrenheit

The formula below can be used to convert between Celsius and Fahrenheit:

°F = (°C × 1.8) + 32

Fahrenheit to Celsius

Use the formula shown below to convert between Fahrenheit and Celsius:

°C = (°F – 32) ÷ 1.8

Celsius to Kelvin

The formula below can be used to convert between Celsius and Kelvin:

K = °C + 273.15

Kelvin to Celsius

The formula below can be used to convert Kelvin to Celsius:

°C = K – 273.15

Fahrenheit to Kelvin

Using the formula above, convert Fahrenheit to Celsius, then use the Celsius to Kelvin conversion formula to convert Fahrenheit to Kelvin:

K = (°F – 32) ÷ 1.8 + 273.15

Kelvin to Fahrenheit

Use the formula above to convert Kelvin to Celsius, then the Celsius to Fahrenheit conversion formula to convert Kelvin to Fahrenheit:

°F = (°C × 1.8) + 32

What is the best temperature scale?

Depending on the circumstance, every temperature scale has advantages and disadvantages. For instance, while the Fahrenheit scale is more widely used in the United States, the Celsius scale is more frequently used in scientific research. In scientific applications where absolute zero is a crucial reference point, the Kelvin scale is frequently used.


Anyone who needs to work with temperature data needs to understand the differences between Celsius, Fahrenheit, and Kelvin. Knowing how to convert between these scales will help you to make sure that the units you use in your calculations are the right ones. Understanding temperature scales is a crucial skill whether you’re a scientist, engineer, or just someone who wants to know how to dress for the weather.
