To convert Celsius (°C) to Kelvin (K), you simply add 273 to the Celsius temperature. The formula is:
Kelvin (K) = Celsius (°C) + 273
For example, if the temperature is 25°C, the conversion to Kelvin would be:
25°C + 273 = 298 K
This is because the Kelvin scale starts at absolute zero, which is -273°C. So, adding 273 to a Celsius temperature gives the equivalent temperature in Kelvin.
