Celsius to Kelvin Converter: Usage, Formulas, and Origin


The Celsius to Kelvin converter is a convenient tool for performing temperature conversions between these two commonly used units of measurement. This article will guide you through the use of this converter, the mathematical formulas employed for conversions, and also delve into the origin of the Kelvin unit of measurement.

How the Celsius to Kelvin Converter Works:

The Celsius to Kelvin converter utilizes simple mathematical formulas to execute conversions between these temperature units. Here are the conversion formulas used:

Conversion from Celsius to Kelvin: Kelvin = Celsius + 273.15

Conversion from Kelvin to Celsius: Celsius = Kelvin - 273.15

Using the Celsius to Kelvin Converter:

The Celsius to Kelvin converter is user-friendly. Follow these steps to perform a conversion:

Step 1: Input the value in degrees Celsius that you wish to convert into the provided space.

Step 2: The converter will automatically compute and display the result in Kelvin just below the Celsius input field.

Step 3: Should you want to convert from Kelvin to Celsius, enter the Kelvin value in the designated second input field.

Step 4: The result in Celsius will be automatically shown below the Kelvin input field.

Example: Convert 25 degrees Celsius to Kelvin and 300 Kelvin to degrees Celsius.


25 degrees Celsius + 273.15 ≈ 298.15 Kelvin

300 Kelvin - 273.15 ≈ 26.85 degrees Celsius


25 degrees Celsius is approximately equivalent to 298.15 Kelvin.

300 Kelvin is approximately equivalent to 26.85 degrees Celsius.

Note on the Origin of the Kelvin Unit of Measurement:

The Kelvin unit of measurement is used to express temperature in the International System of Units (SI). It is based on the absolute thermodynamic scale, where zero Kelvin (0 K) represents absolute zero, the lowest attainable temperature, at which molecules possess no thermal energy. The Kelvin scale was named in honor of Lord Kelvin, a 19th-century Scottish physicist who played a pivotal role in the development of thermodynamic laws and our understanding of heat and temperature.


The Celsius to Kelvin converter is a practical and useful tool for scientists, professionals, and even daily users when temperature conversions are required. By utilizing the simple conversion formulas outlined in this article, you can efficiently and precisely perform temperature conversions for various purposes. These online converters are valuable for numerous practical applications where temperature conversions are necessary.
