Difference is 273.15. Here are formulas: K = C + 273.15 C = K - 273.15 Difference is 273.15. Here are formulas: [°C] = [K] − 273.15 [K] = [°C] + 273.15
"K" is the Kelvin scale which is useful in physics as it measures absolute heat. Absolute Zero is 0 degrees Kelvin which theoretically contains absolutely no heat and is the coldest anything can be. The freezing-to-boiling range of water is 273K to 373K.
"C" is the Celsius or Centigrade scale which is most useful in chemistry involving water, as the freezing-to-boiling range of water is 0C to 100C. Absolute Zero is -273.15C. 1 "Kelvin" is also a dynamic calculation unit and as such is = to 1 "Centigrade". Thus, speaking about an "on-off" controller of temperature whose Setpoit may be set: 18 C heating element on, 20 C it is off, we say the differential (or delta, or hysteresis) is negative and equals 2 K.

Kelvin temperatures are based on absolute zero, not the freezing point of water. The degree intervals are the same size as Celsius degrees, but begin 273.15 degrees lower. To calculate Kelvin, simply add 273.15 to the Celsius temperature value. To calculate the Celsius temperature, subtract 273.15 from the K value. °C = K - 273.15 K = °C + 273.15 Note that temperatures on the Kelvin scale do not use degree marks (°), just the letter K. Example : for the temperature 100 K, 100 K = -173.15°C Example : for the temperature 20 °C, 20 °C = 293.15 K
