Conversion Formula
The formula to convert Celsius to kelvin is simple: K = °C + 273.15. Celsius measures temperature relative to the freezing point of water, while kelvin measures from absolute zero, the coldest possible temperature.
This formula works because the kelvin scale starts 273.15 degrees below the freezing point of water, which is 0°C. By adding 273.15, the Celsius temperature moves into the absolute scale used in scientific calculations.
For example, converting 450°C:
450 + 273.15 = 723.15 K
Conversion Example
- Convert 100°C to kelvin:
- Start with 100°C
- Add 273.15 to 100 → 100 + 273.15
- Result is 373.15 K
- Convert -50°C to kelvin:
- Start with -50°C
- Add 273.15 → -50 + 273.15
- Result is 223.15 K
- Convert 0°C to kelvin:
- Start with 0°C
- Add 273.15 → 0 + 273.15
- Result is 273.15 K
- Convert 37°C to kelvin:
- Start with 37°C
- Add 273.15 → 37 + 273.15
- Result is 310.15 K

Conversion Definitions
Celsius: Celsius is a temperature scale where 0 degrees represents the freezing point of water and 100 degrees represents the boiling point at standard atmospheric pressure. It’s widely used for everyday temperature measurement in many countries and scientific contexts.
Kelvin: Kelvin is the SI unit of temperature based on absolute zero, the lowest possible temperature where particles have minimum thermal motion. It starts at zero kelvin and is mostly used in scientific fields to measure extremely low or high temperatures accurately.
Conversion FAQs
Why do we add 273.15 to convert Celsius to kelvin?
Adding 273.15 shifts the Celsius scale to the absolute zero point, which is zero kelvin. Since Celsius zero is the freezing point of water, but kelvin zero is absolute zero, the difference between these points is 273.15 degrees, so adding this value aligns Celsius temperatures to kelvin.
Can the kelvin temperature ever be negative?
No, kelvin temperatures cannot be negative because kelvin starts at absolute zero, the lowest theoretical temperature possible. Temperatures below absolute zero are not physically meaningful, thus kelvin scale has no negative values.
Is 450 Celsius a high temperature in kelvin terms?
Yes, 450 degrees Celsius converts to 723.15 kelvin, which is relatively hot temperature. It’s used in processes requiring high heat like some industrial manufacturing or scientific experiments.
Can I convert kelvin back to Celsius easily?
Yes, converting kelvin to Celsius is straightforward: subtract 273.15 from the kelvin temperature. For example, 723.15 K minus 273.15 equals 450°C, reversing the conversion.
Why is kelvin preferred over Celsius in science?
Kelvin is preferred because it starts from absolute zero, providing an absolute scale for temperature. This makes calculations involving thermodynamics and physical constants more accurate and consistent compared to relative scales like Celsius.
