450 degrees Celsius equals 723.15 kelvin.
The conversion from Celsius to kelvin is done by adding 273.15 to the Celsius temperature value. Since kelvin starts at absolute zero, the zero point in Celsius (-273.15°C) corresponds to 0 kelvin, so adding this constant shifts the scale appropriately.

Conversion Formula
The formula to convert Celsius (°C) to kelvin (K) is:
K = °C + 273.15
This formula works because Celsius and kelvin scales have the same unit size, but kelvin starts at absolute zero, which is -273.15°C. So, by adding 273.15, the Celsius value is shifted to the kelvin scale.
For example, converting 450°C:
- Start with 450°C
- Add 273.15 to 450: 450 + 273.15 = 723.15
- The equivalent temperature in kelvin is 723.15 K
Conversion Example
- Convert 100°C to kelvin:
- 100 + 273.15 = 373.15 K
- So, 100°C equals 373.15 kelvin.
- Convert -50°C to kelvin:
- -50 + 273.15 = 223.15 K
- Therefore, -50°C is 223.15 kelvin.
- Convert 0°C to kelvin:
- 0 + 273.15 = 273.15 K
- Zero degrees Celsius corresponds to 273.15 kelvin.
- Convert 37°C to kelvin:
- 37 + 273.15 = 310.15 K
- Body temperature in kelvin is 310.15.

Conversion Definitions
Celsius: Celsius is a temperature scale where zero degrees marks the freezing point of water and one hundred degrees the boiling point, at standard atmospheric pressure. It is widely used for everyday temperature measurements around the world, especially outside scientific contexts.
Kelvin: Kelvin is the SI base unit for temperature, starting at absolute zero, the coldest possible temperature. One kelvin is equal in size to one Celsius degree, but the kelvin scale does not use negative numbers, making it important for scientific measurements.
Conversion FAQs
Can Celsius values be negative when converting to kelvin?
Yes, Celsius temperatures can be negative but kelvin values cannot. When converting, adding 273.15 shifts the scale so even negative Celsius become positive kelvin. For example, -100°C converts to 173.15 K.
Why is 273.15 added to Celsius to get kelvin?
Because kelvin scale starts at absolute zero (-273.15°C), adding 273.15 adjusts the Celsius temperature to the kelvin reference point. This keeps unit size the same but shifts zero to absolute zero.
Is kelvin used in everyday weather reports?
No, kelvin is not common for daily weather. Celsius or Fahrenheit is preferred because kelvin values are higher and less intuitive for public use. Kelvin mostly appears in scientific fields.
What is the precision of the conversion formula?
The formula K = °C + 273.15 is precise to two decimal places, which is enough for most practical purposes. Scientific work requiring higher precision can use more exact constants or calibration.
Does the kelvin scale ever use negative numbers?
No, the kelvin scale never has negative values because zero kelvin is absolute zero, the lowest temperature possible. Negative kelvin would imply temperatures below absolute zero, which violates physical laws.
