Table of Contents
To convert Celsius to kelvin, you add 273.15 to the Celsius temperature. This is because kelvin scale starts at absolute zero, which is -273.15°C. So, 26°C plus 273.15 gives the equivalent temperature in kelvin.

Conversion Formula
The formula to convert Celsius (°C) to kelvin (K) is:
K = °C + 273.15
This works because the kelvin scale is based on absolute zero, which is the lowest possible temperature where particles have minimum thermal motion. Absolute zero equals -273.15°C. So, to get kelvin, you add 273.15 to the Celsius temperature.
For example, converting 26°C to kelvin:
- Start with the Celsius temperature: 26°C
- Add 273.15: 26 + 273.15 = 299.15 K
- The result is 299.15 kelvin
Conversion Example
- Convert 15°C to kelvin:
- Start with 15°C
- Add 273.15: 15 + 273.15 = 288.15 K
- Result: 288.15 kelvin
- Convert -10°C to kelvin:
- Start with -10°C
- Add 273.15: -10 + 273.15 = 263.15 K
- Result: 263.15 kelvin
- Convert 0°C to kelvin:
- Start with 0°C
- Add 273.15: 0 + 273.15 = 273.15 K
- Result: 273.15 kelvin
- Convert 40.5°C to kelvin:
- Start with 40.5°C
- Add 273.15: 40.5 + 273.15 = 313.65 K
- Result: 313.65 kelvin
- Convert 100°C to kelvin:
- Start with 100°C
- Add 273.15: 100 + 273.15 = 373.15 K
- Result: 373.15 kelvin

Conversion Definitions
Celsius: Celsius, also called centigrade, is a temperature scale where 0 degrees is the freezing point of water and 100 degrees is the boiling point at standard atmospheric pressure. The scale is widely use in most countries for weather forecasting and scientific measurements.
Kelvin: Kelvin is the SI base unit of temperature measuring absolute temperature starting from absolute zero, the lowest limit where molecular motion stops. The kelvin scale is used in physics and chemistry to express thermodynamic temperature without negative numbers.
Conversion FAQs
Why is 273.15 added to Celsius to get kelvin?
273.15 is the temperature difference between absolute zero and the freezing point of water on Celsius scale. Adding 273.15 shifts the Celsius value so that 0 K represents absolute zero, making kelvin an absolute temperature scale starting from the coldest possible temperature.
Can kelvin values be negative like Celsius?
No, kelvin values can’t be negative because kelvin starts at absolute zero, which is the lowest possible temperature. Negative kelvin would mean temperatures below absolute zero, which is physically impossible according to thermodynamics.
How precise is the kelvin value when converting from Celsius?
The kelvin value is precise up to decimal points depending on the measurement accuracy of Celsius temperature. The constant 273.15 is exact, so the precision mostly depends on the original Celsius value and the number of decimal places used in calculations.
Is the conversion formula the same in all conditions?
The formula K = °C + 273.15 holds true under normal atmospheric pressure and for temperatures used in everyday contexts. Extreme conditions or different pressure levels don’t change this formula since kelvin and Celsius scales have a fixed offset.
Why use kelvin instead of Celsius in science?
Kelvin scale is preferred in scientific fields because it starts at absolute zero, making calculations involving thermal energy and gas laws straightforward. It avoids negative values that complicate equations and better represents absolute thermal energy.
