450 degrees Celsius equals 723.15 kelvin.
The conversion from Celsius to kelvin involves adding 273.15 to the Celsius temperature. This is because kelvin starts at absolute zero, which is -273.15°C, so we shift the Celsius scale up to match kelvin values.

Conversion Formula
The formula to convert Celsius to kelvin is simple: add 273.15 to the Celsius temperature. This works because the kelvin scale starts at absolute zero (-273.15°C), so zero kelvin equals -273.15 degrees Celsius.
Formula: K = °C + 273.15
Step-by-step example for 450°C:
- Start with the Celsius temperature: 450
- Add 273.15: 450 + 273.15 = 723.15
- The result is 723.15 kelvin
Conversion Example
- Convert 100°C to kelvin:
- Take 100°C
- Add 273.15: 100 + 273.15 = 373.15
- Result: 373.15 K
- Convert -50°C to kelvin:
- Take -50°C
- Add 273.15: -50 + 273.15 = 223.15
- Result: 223.15 K
- Convert 0°C to kelvin:
- Take 0°C
- Add 273.15: 0 + 273.15 = 273.15
- Result: 273.15 K
- Convert 37°C to kelvin:
- Take 37°C
- Add 273.15: 37 + 273.15 = 310.15
- Result: 310.15 K

Conversion Definitions
Celsius: Celsius or centigrade is a temperature scale where water freezes at 0 degrees and boils at 100 degrees under standard atmospheric pressure. It is widely used for weather, cooking, and scientific temperature measurements around the world.
Kelvin: Kelvin is the SI unit of temperature, starting at absolute zero (-273.15°C) where all molecular motion stops. It is used mainly in scientific fields to measure thermodynamic temperature without negative numbers, making calculations easier.
Conversion FAQs
Can the Celsius to kelvin conversion result in negative kelvin values?
No, kelvin scale starts at absolute zero (0 K), which is -273.15°C. That means kelvin values cannot be negative. Any Celsius temperature below -273.15°C is physically impossible, so conversions below that don’t exist in real terms.
Why is 273.15 added exactly, not a rounded number?
The value 273.15 is the exact offset between Celsius and kelvin scales based on thermodynamic definitions. Using a rounded number like 273 would cause small errors in precise calculations, so 273.15 maintains accuracy.
Does converting 450°C to kelvin change the physical state of a substance?
Conversion itself does not change the physical state; it only expresses the same temperature in a different unit. Whether a substance melts or boils depends on its actual temperature, not the scale used.
Is the Celsius to kelvin formula valid for all temperature ranges?
Yes, the formula K = °C + 273.15 works for all temperatures within physical limits. It’s a linear relationship, so it applies from absolute zero to extremely high temperatures without exceptions in theory.
How accurate is the kelvin value when converting from Celsius?
The conversion is very accurate when using the formula with 273.15. Minor inaccuracies can arise from measurement errors of the Celsius temperature itself, but the mathematical conversion is exact.
