The conversion of 5°C to Kelvin results in 278.15 K.
To convert Celsius to Kelvin, you add 273.15 to the Celsius value. This is because Kelvin starts at absolute zero, which is -273.15°C, and increases in the same increments as Celsius. So, 5°C plus 273.15 gives the temperature in Kelvin.
Conversion Result
5°C equals 278.15 Kelvin.

Conversion Formula
The formula to convert Celsius to Kelvin is K = C + 273.15. It works because Kelvin scale starts at absolute zero, which is -273.15°C. By adding 273.15 to Celsius, you shift the scale to start from absolute zero, making it accurate for scientific use. For example, 5°C + 273.15 = 278.15 K.
Conversion Example
- Convert 10°C to Kelvin:
- Start with Celsius value: 10°C
- Add 273.15: 10 + 273.15
- Result: 283.15 Kelvin
- Convert -15°C to Kelvin:
- Start with Celsius value: -15°C
- Add 273.15: -15 + 273.15
- Result: 258.15 Kelvin
- Convert 25°C to Kelvin:
- Start with Celsius value: 25°C
- Add 273.15: 25 + 273.15
- Result: 298.15 Kelvin
- Convert 0°C to Kelvin:
- Start with Celsius value: 0°C
- Add 273.15: 0 + 273.15
- Result: 273.15 Kelvin
- Convert 20°C to Kelvin:
- Start with Celsius value: 20°C
- Add 273.15: 20 + 273.15
- Result: 293.15 Kelvin

Conversion Definitions
c: Celsius, a temperature scale where 0°C is the freezing point of water and 100°C is the boiling point at standard atmospheric pressure, used globally for everyday temperature measurements.
kelvin: Kelvin, the base unit of temperature in the International System, starting at absolute zero (-273.15°C), measuring thermodynamic temperature with increments identical to Celsius but offset for absolute zero.
Conversion FAQs
How do I convert Celsius to Kelvin manually?
To convert Celsius to Kelvin manually, simply add 273.15 to the Celsius temperature. For example, for 5°C, 5 + 273.15 equals 278.15 Kelvin. This shift accounts for the difference in starting points of the two scales.
Why is Kelvin used in scientific measurements instead of Celsius?
Kelvin is used because it starts at absolute zero, the point where particles have minimum thermal motion, providing a true zero point for thermodynamic calculations, making it more precise for scientific purposes than Celsius.
Can I convert negative Celsius temperatures to Kelvin?
Yes, negative Celsius temperatures are converted by adding 273.15, so for example, -10°C becomes 263.15 Kelvin. The Kelvin scale remains positive because it only measures absolute temperature starting from zero.
Are Kelvin and Celsius directly proportional?
Yes, they are directly proportional, differing only by a fixed offset of 273.15. Changes in Celsius are equal to changes in Kelvin, just shifted by this constant. So, a 1°C increase equals a 1 Kelvin increase.
What is the significance of absolute zero on the Kelvin scale?
Absolute zero, at 0 Kelvin, is the theoretical temperature where particles possess minimum energy, and all thermal motion stops. It is the lowest possible temperature and marks the starting point of the Kelvin scale.
