900 degrees Celsius is equal to 1173.15 kelvin.
To convert Celsius to kelvin, you add 273.15 to the Celsius temperature. This is because kelvin and Celsius scales are offset by 273.15 units, but they have the same magnitude per degree. So, 900 + 273.15 gives the kelvin value.

Conversion Formula
The formula to convert Celsius (°C) to kelvin (K) is very simple: K = °C + 273.15. The kelvin scale starts at absolute zero, which is −273.15°C, so to find the kelvin temperature you add 273.15 to the Celsius temperature.
This works because kelvin and Celsius degrees have the same size, but their zero points differ. Celsius zero is freezing water, while kelvin zero is absolute zero, the lowest possible temperature.
Example:
- Given temperature: 900°C
- Add 273.15 to 900: 900 + 273.15 = 1173.15 K
- So, 900°C equals 1173.15 kelvin.
Conversion Example
- Convert 250°C to kelvin:
- Start with 250.
- Add 273.15 → 250 + 273.15 = 523.15 K.
- Result: 250°C is 523.15 kelvin.
- Convert −40°C to kelvin:
- Start with −40.
- Add 273.15 → −40 + 273.15 = 233.15 K.
- Result: −40°C equals 233.15 kelvin.
- Convert 0°C to kelvin:
- Start with 0.
- Add 273.15 → 0 + 273.15 = 273.15 K.
- Result: 0°C equals 273.15 kelvin.
- Convert 100°C to kelvin:
- Start with 100.
- Add 273.15 → 100 + 273.15 = 373.15 K.
- Result: 100°C equals 373.15 kelvin.

Conversion Definitions
Celsius: Celsius is a temperature scale where zero degrees is the freezing point of water and 100 degrees is its boiling point at sea level. It is used commonly around the world for weather, science, and daily temperature measurements, with increments called degrees Celsius (°C).
Kelvin: Kelvin is a temperature scale used in science that starts at absolute zero, the lowest theoretical temperature. Unlike Celsius, kelvin does not use degrees but kelvin units (K). One kelvin equals one degree Celsius in size, but its zero point is shifted to −273.15°C.
Conversion FAQs
Why do I add exactly 273.15 to convert Celsius to kelvin?
The Celsius and kelvin scales have the same size per degree, but the kelvin scale starts at absolute zero, which is −273.15°C. Adding 273.15 shifts the zero point from freezing water to absolute zero, making sure the temperature is correctly expressed in kelvin.
Can kelvin values be negative when converted from Celsius?
No, kelvin values cannot be negative because the kelvin scale starts at absolute zero, the lowest possible temperature. If Celsius is below −273.15, the conversion would result in negative kelvin, which is physically impossible.
Is the kelvin scale used in everyday life?
The kelvin scale is mainly used in scientific and engineering fields, like physics and chemistry, where precise temperature measurements are needed. Everyday weather and cooking temperatures use Celsius or Fahrenheit instead of kelvin.
How precise is the conversion between Celsius and kelvin?
The conversion is exact and linear. Since one kelvin equals one degree Celsius in size, only the offset of 273.15 is added. This makes conversions highly precise with no rounding errors except from decimal limitations.
What happens if I use 273 instead of 273.15 in conversion?
Using 273 instead of 273.15 gives a slight error in temperature conversion, about 0.15 kelvin off. For rough estimates, it can be fine, but for scientific work, the 273.15 value is necessary for accuracy.
