The temperature 22°C converts to 295.15 Kelvin.
To convert 22°C to Kelvin, add 273.15 to the Celsius value because Kelvin starts at absolute zero, which is -273.15°C. So, 22°C + 273.15 = 295.15K. This method shifts the scale from Celsius, which is based on the freezing point of water, to Kelvin, the SI base unit for temperature.

Conversion Formula
The formula to convert Celsius to Kelvin is simple: K = C + 273.15. This works because Kelvin scale starts at absolute zero, which is 273.15 degrees below the Celsius scale. When you add 273.15 to any Celsius temperature, you shift the scale to Kelvin. For example, 22°C plus 273.15 equals 295.15K. This conversion is straightforward and ensures the temperature is on an absolute scale for scientific purposes.
Conversion Example
- Convert 0°C to Kelvin:
- Start with 0°C.
- Add 273.15 to 0°C.
- 0 + 273.15 = 273.15K.
- Convert -10°C to Kelvin:
- -10°C plus 273.15.
- -10 + 273.15 = 263.15K.
- Convert 37°C to Kelvin:
- 37°C plus 273.15.
- 37 + 273.15 = 310.15K.
- Convert 100°C to Kelvin:
- 100°C plus 273.15.
- 100 + 273.15 = 373.15K.

Conversion Definitions
“c” stands for Celsius, a temperature scale where 0°C is the freezing point of water and 100°C is boiling point at standard pressure. It is based on the properties of water and used worldwide for most temperature measurements.
“kelvin” is the SI base unit for temperature, starting at absolute zero (0K), the point where particles have minimum thermal motion. Its units are the same size as Celsius degrees, but it begins at zero, making it ideal for scientific calculations.
Conversion FAQs
Why do I need to add 273.15 to Celsius to get Kelvin?
This addition sets the zero point of Kelvin at absolute zero, which is -273.15°C. It aligns the Celsius scale with the Kelvin scale, enabling temperatures to be expressed on an absolute scale used in scientific contexts, ensuring consistency across measurements.
Is Kelvin always higher than Celsius?
Yes, because Kelvin starts at absolute zero, which is -273.15°C. Therefore, any positive Celsius temperature will have a Kelvin equivalent that is higher. For negative Celsius temperatures, Kelvin values are still positive but less than zero in Celsius.
Can I convert Celsius to Kelvin without adding 273.15?
No, because the scales are offset by 273.15 degrees. Without adding this value, the Kelvin temperature would be incorrect, especially at temperatures below water’s freezing point. The formula, K = C + 273.15, is necessary for accurate conversion.
What is the significance of Kelvin in scientific measurements?
Kelvin provides an absolute temperature scale that starts at absolute zero, the point where particles have minimal energy. It allows scientists to perform calculations involving thermal energy, thermodynamics, and kinetic theory without negative values.
