Celsius to Kelvin

Celsius to Kelvin Conversion

The Celsius to Kelvin conversion is a mathematical process to convert a temperature value from the Celsius scale to the Kelvin scale. Kelvin is the unit of temperature in the International System of Units (SI), and it is often used in scientific and engineering contexts. The Kelvin scale is an absolute temperature scale, meaning that 0 Kelvin represents the absolute zero temperature, the lowest possible temperature where molecular motion stops. The conversion formula from Celsius to Kelvin is simple:

Kelvin = Celsius + 273.15


  • Kelvin is the temperature in Kelvin.
  • Celsius is the temperature in Celsius.

To convert a temperature from Celsius to Kelvin, you simply add 273.15 to the Celsius temperature value.

For example:

    To convert 25 degrees Celsius to Kelvin:
    Kelvin = 25 + 273.15
    Kelvin  298.15 K

    To convert -10 degrees Celsius to Kelvin:
    Kelvin = -10 + 273.15
    Kelvin  263.15 K

The Kelvin scale is often used in scientific calculations and engineering where absolute temperature values are important. It's important to note that while the Kelvin scale is similar in magnitude to the Celsius scale (they have the same size degree), Kelvin is an absolute scale starting from absolute zero, while Celsius starts from the freezing point of water (0C).
