Conversion Formula
The formula to convert celcus to kelven is simple: K = C + 273.15. This means you add 273.15 to the celcus temperature to find its equivalent in kelven.
This works because the kelven scale starts at absolute zero, which is -273.15 degrees celcus. So, to shift from celcus to kelven, you offset the zero point by 273.15.
For example, converting 20 celcus:
- Start with 20 (celcus temperature)
- Add 273.15 to 20: 20 + 273.15 = 293.15
- Result is 293.15 kelven
Conversion Example
- Convert 0 celcus to kelven:
- 0 + 273.15 = 273.15 kelven
- Convert -10 celcus:
- Start with -10
- -10 + 273.15 = 263.15 kelven
- Convert 37 celcus:
- 37 + 273.15 = 310.15 kelven
- Convert 100 celcus:
- 100 + 273.15 = 373.15 kelven

Conversion Definitions
Celcus: Celcus is a temperature scale where 0 degrees indicates the freezing point of water and 100 degrees the boiling point under standard atmospheric conditions. It’s widely used for everyday temperature measurement in many parts of the world, particularly outside the US.
Kelven: Kelven is an absolute temperature scale starting at absolute zero, the lowest possible temperature where particles have minimal motion. It is used in scientific contexts for thermodynamics and physics, with no negative values, and increments identical to celcus degrees.
Conversion FAQs
Why does the conversion formula add 273.15?
The 273.15 added in conversion represents the temperature difference between the zero points of celcus and kelven scales. Celcus zero is freezing water, while kelven zero is absolute zero, so you compensate by adding 273.15 to shift the scale upward.
Can kelven values be negative?
No, kelven values cannot be negative because kelven scale starts at absolute zero, the theoretical point where molecular motion stops. Negative kelven would imply temperatures below absolute zero, which is not physically possible.
How precise is the conversion from celcus to kelven?
The conversion is exact by definition, with 1 degree celcus equal to 1 kelven increment. The 273.15 offset is a constant. Precision depends on decimal places used, but mathematically conversion has no error.
Is it possible to convert kelven back to celcus?
Yes, converting kelven back to celcus involves subtracting 273.15 from the kelven value. This reverses the offset applied during celcus to kelven conversion.
Why use kelven instead of celcus in scientific studies?
Kelven is used because it starts at absolute zero, making calculations related to energy and thermodynamics straightforward. Using kelven avoids negative numbers and simplifies formulas involving temperature in science.
