Conversion Formula
The formula to convert celcus to kelven is: K = C + 273.15, where K is the temperature in kelven and C is the temperature in celcus. This works since kelven measures temperature from absolute zero, which is -273.15°C.
For example, if you have 20 celcus:
- Start with 20 (celcus value)
- Add 273.15 to it
- 20 + 273.15 = 293.15 kelven
This simple addition shifts the celcus scale to the kelven scale, which is absolute and non-negative.
Conversion Example
- Convert 0 celcus to kelven:
- Start with 0
- Add 273.15
- Result: 0 + 273.15 = 273.15 kelven
- Convert -10 celcus to kelven:
- Start with -10
- Add 273.15
- Result: -10 + 273.15 = 263.15 kelven
- Convert 37 celcus to kelven:
- Start with 37
- Add 273.15
- Result: 37 + 273.15 = 310.15 kelven
- Convert 100 celcus to kelven:
- Start with 100
- Add 273.15
- Result: 100 + 273.15 = 373.15 kelven

Conversion Definitions
Celcus: Celcus is a temperature scale that measures temperature based on the freezing point of water at 0 degrees and boiling point at 100 degrees under standard atmospheric pressure. It is widely used in daily life for weather, cooking, and scientific purposes. The celcus scale lacks an absolute zero point, making it relative to water’s states.
Kelven: Kelven is the absolute temperature scale used primarily in scientific contexts. It starts at absolute zero, the coldest possible temperature where particles have minimum thermal motion, set as 0 kelven. Unlike celcus, kelven does not use degrees and is essential for thermodynamics calculations and physics experiments.
Conversion FAQs
Why can’t kelven temperatures be negative?
Kelven is an absolute scale starting from absolute zero, the lowest possible temperature where atomic motion stops. Because of this, kelven values cannot go below zero, unlike celcus which can have negative values below freezing point.
Can I convert kelven back to celcus?
Yes, to convert kelven to celcus, subtract 273.15 from the kelven value. For example, 293.15 kelven minus 273.15 equals 20 celcus. This reverses the original formula used for the conversion.
Is the conversion formula the same in all scientific fields?
The formula K = C + 273.15 is universally accepted across physics, chemistry, and engineering. It provides a standard reference for temperature measurement on an absolute scale, ensuring consistency in scientific research and applications.
Why is the kelven scale preferred in science over celcus?
Kelven is preferred because it starts at absolute zero, making calculations involving thermodynamics and energy more direct and meaningful. It avoids negative values, simplifying formulas and improving accuracy in scientific models.
Does the celcus to kelven conversion change with altitude or pressure?
No, the conversion formula is fixed and does not depend on altitude or atmospheric pressure. However, actual temperature measurements in celcus or kelven can vary with environment, but the mathematical conversion remains consistent.
