Conversion Formula
The formula to convert Celsius (°C) to kelvin (K) is:
K = °C + 273.15
This formula works because kelvin starts at absolute zero, which is the lowest possible temperature where particles have minimum thermal motion. Absolute zero equals -273.15 °C. So kelvin just shifts the Celsius scale up by 273.15 units.
Example calculation for 80 °C:
- Start with 80 °C
- Add 273.15: 80 + 273.15 = 353.15
- Result is 353.15 K
Conversion Example
- Convert 25 °C to kelvin:
- Take 25 °C
- Add 273.15: 25 + 273.15 = 298.15 K
- So, 25 °C equals 298.15 K
- Convert -40 °C to kelvin:
- Start with -40 °C
- Add 273.15: -40 + 273.15 = 233.15 K
- Therefore, -40 °C is 233.15 K
- Convert 0 °C to kelvin:
- Begin with 0 °C
- Add 273.15: 0 + 273.15 = 273.15 K
- Result is 273.15 K
- Convert 100 °C to kelvin:
- Take 100 °C
- Add 273.15: 100 + 273.15 = 373.15 K
- So, 100 °C equals 373.15 K

Conversion Definitions
Celsius: Celsius is a temperature scale where zero degrees marks the freezing point of water and 100 degrees marks boiling point at standard atmospheric pressure. It is widely used for weather, cooking, and scientific measurements around the world.
Kelvin: Kelvin is an absolute temperature scale starting at absolute zero, the lowest theoretical temperature possible where particles have no thermal energy. It is commonly used in physics and chemistry to measure temperatures without negative values.
Conversion FAQs
Can kelvin temperatures ever be negative?
No, kelvin temperatures cannot be negative because the scale starts at absolute zero, which is the coldest temperature possible. Unlike Celsius or Fahrenheit, kelvin measures thermal energy directly and zero kelvin means no particle motion at all.
Why do we add 273.15 to convert Celsius to kelvin?
Adding 273.15 shifts the Celsius scale to start at absolute zero on the kelvin scale. Since absolute zero equals -273.15 °C, by adding this value, the temperature is adjusted to kelvin’s zero point, making all kelvin values positive.
Is kelvin used outside of science?
Kelvin is mostly used in scientific fields like physics, chemistry, and engineering where precise temperature measurement is needed. For everyday use, Celsius or Fahrenheit are usually preferred because they relate more directly to human experience.
How precise is the conversion from Celsius to kelvin?
The conversion formula is exact, as kelvin is defined based on Celsius with the fixed offset 273.15. Any variations come only from measuring the Celsius temperature, not the conversion itself.
Can I convert kelvin back to Celsius?
Yes, you convert kelvin to Celsius by subtracting 273.15 from the kelvin value. For example, 300 K minus 273.15 equals 26.85 °C.
