How to Convert Celsius to Kelvin

To convert a temperature from degrees Celsius (°C) to Kelvin (K), you need to use the following formula:

K = °C + 273.15

Here are the steps:

  1. Take the temperature value in degrees Celsius.
  2. Add 273.15 to it.
  3. The result is the equivalent temperature in Kelvin.

For example, to convert 25°C to Kelvin:

25°C + 273.15 = 298.15K

So 25 degrees Celsius is equal to 298.15 Kelvin.

The reason you add 273.15 is that the Kelvin scale starts at the absolute zero of temperature, which is -273.15°C. So adding 273.15 shifts the Celsius scale to start at 0 on the Kelvin scale.
