Celsius to Kelvin Converter
Convert temperatures between Celsius and Kelvin scales with our easy-to-use calculator. Perfect for scientific calculations, education, and temperature conversions.
Step 1: Enter Temperature
Understanding Temperature Scales
The Celsius scale is based on water’s freezing (0°C) and boiling (100°C) points. The Kelvin scale is an absolute thermodynamic temperature scale where 0K is absolute zero, the theoretical lowest possible temperature.
Step 2: Conversion Options
Conversion Formula
To convert Celsius to Kelvin: K = °C + 273.15
To convert Kelvin to Celsius: °C = K – 273.15

Temperature Conversion Formula
Celsius to Kelvin: K = °C + 273.15
The Kelvin scale is an absolute temperature scale that starts at absolute zero (0K), the theoretical point where particles have minimal thermal motion. To convert from Celsius to Kelvin, simply add 273.15 to the Celsius temperature.
Kelvin to Celsius: °C = K – 273.15
To convert from Kelvin to Celsius, subtract 273.15 from the Kelvin temperature. This conversion is straightforward because both scales use the same degree size, differing only in their zero points.
Temperature Scale History
Celsius Scale
Developed by Swedish astronomer Anders Celsius in 1742, originally with 0° as the boiling point and 100° as the freezing point of water. This was reversed after his death to the modern scale we use today.
Kelvin Scale
Named after British physicist William Thomson, 1st Baron Kelvin, who developed the concept of an absolute temperature scale in 1848. The Kelvin scale is fundamental in scientific work, particularly in physics and chemistry.
