1 Kelvin (K) and 0 degrees Celsius (°C) are related by the following:

* 0°C is equal to 273.15 K.

This means that there is a shift of 273.15 units between the Celsius and Kelvin scales.

Here's a breakdown:

* Kelvin scale: Starts at absolute zero (0 K), which is the theoretical point where all molecular motion stops. It's an absolute temperature scale, meaning there are no negative values.

* Celsius scale: Starts at the freezing point of water (0°C) and has a defined boiling point of water at 100°C.

Key takeaways:

* To convert Celsius to Kelvin, add 273.15.

* To convert Kelvin to Celsius, subtract 273.15.
