What is the formula for converting kelvin into Celsius?

Answer 1

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
