Conversion Formula
The formula to convert Celsius (°C) to kelvin (K) is:
K = °C + 273.15
This formula works because the kelvin scale is an absolute scale starting at absolute zero, which is -273.15°C. By adding 273.15 to a Celsius temperature, you shift the starting point to zero kelvin.
For example, converting 25°C to kelvin step-by-step:
- Start with the Celsius temperature: 25°C
- Add 273.15 to it: 25 + 273.15
- Result: 298.15 K
Conversion Example
- Convert 0°C to kelvin:
- Start with 0°C
- Add 273.15: 0 + 273.15
- Result: 273.15 K
- Convert -10°C to kelvin:
- Start with -10°C
- Add 273.15: -10 + 273.15
- Result: 263.15 K
- Convert 37°C to kelvin:
- Start with 37°C
- Add 273.15: 37 + 273.15
- Result: 310.15 K
- Convert 100°C to kelvin:
- Start with 100°C
- Add 273.15: 100 + 273.15
- Result: 373.15 K

Conversion Definitions
Celsius (°C): Celsius is a temperature scale based on water freezing at 0 degrees and boiling at 100 degrees under standard atmospheric pressure. It is widely used in everyday temperature measurements and scientific contexts, providing a relative scale centered on water’s physical properties.
Kelvin (K): Kelvin is an absolute temperature scale starting at absolute zero, the point where particles have minimum thermal motion. It is used in science and engineering to measure temperature without negative values, with each kelvin equal in magnitude to one degree Celsius.
Conversion FAQs
Why do we add 273.15 when converting Celsius to kelvin?
Adding 273.15 shifts the Celsius temperature to an absolute scale starting from zero kelvin, which is absolute zero. Since Celsius zero is below absolute zero by 273.15 degrees, adding this number aligns the scales correctly, making temperature comparisons in physics and chemistry consistent.
Can kelvin temperatures be negative?
No, kelvin temperatures cannot be negative because kelvin is an absolute scale starting at absolute zero, the lowest possible temperature. Temperatures below absolute zero are not physically meaningful, so kelvin values are always zero or positive.
Is 0 kelvin the same as -273.15 Celsius?
Yes, 0 K equals -273.15°C exactly. This temperature is absolute zero, the theoretical point where particles have minimum thermal energy and motion. It represents the lowest temperature achievable in nature or laboratory conditions.
Why use kelvin instead Celsius in science?
Kelvin provides an absolute reference point at zero thermal energy, making it useful for scientific calculations involving thermodynamics and physical laws. Celsius can have negative values, which complicates formulas; kelvin avoids this by starting at zero.
How precise is the conversion between Celsius and kelvin?
The conversion is exact by definition, as 0 K is defined as -273.15°C. However, practical measurements of temperature may have slight uncertainties, but the formula itself is precise and universally accepted.
