How to Convert Celsius to Kelvin
This conversion uses an offset formula, so it cannot be described by a single multiplication factor.
Formula: K = °C + 273.15
Reverse: °C = K - 273.15
Step-by-Step Example
- Start with your value in Celsius. For example: 5 °C
- Apply K = °C + 273.15
- The result is: 278.15 K
About Celsius
The Celsius scale sets 0°C as the freezing point and 100°C as the boiling point of water at standard pressure. It is used by most countries worldwide.
Fun Fact: Anders Celsius originally proposed a scale where 100° was freezing and 0° was boiling—it was later reversed!
Common uses: weather, cooking, science.
About Kelvin
The Kelvin scale is the SI unit of temperature that starts at absolute zero (−273.15°C). It is used extensively in scientific research.
Fun Fact: At 0 Kelvin (absolute zero), all molecular motion stops. It has never been fully achieved in a laboratory.
Common uses: physics, astronomy, chemistry.
