22 degrees Celsius equals 295.15 kelvin.
The temperature conversion from Celsius to kelvin involves adding 273.15 to the Celsius value. This accounts for the difference between the Celsius scale, which is based on the freezing point of water, and the kelvin scale, which starts at absolute zero.

Conversion Formula
The formula for converting Celsius (°C) to kelvin (K) is:
K = °C + 273.15
This formula works because the kelvin scale starts at absolute zero, which is -273.15°C. Adding 273.15 shifts the temperature value from the Celsius scale to the kelvin scale, which has no negative numbers.
For example, to convert 22°C to kelvin:
- Start with the Celsius temperature: 22°C
- Add 273.15 to it: 22 + 273.15 = 295.15
- The result is 295.15 K
Conversion Example
-
Convert 10°C to kelvin:
- Start with 10°C
- Add 273.15: 10 + 273.15 = 283.15 K
- Result: 283.15 kelvin
-
Convert -5°C to kelvin:
- Start with -5°C
- Add 273.15: -5 + 273.15 = 268.15 K
- Result: 268.15 kelvin
-
Convert 37.5°C to kelvin:
- Start with 37.5°C
- Add 273.15: 37.5 + 273.15 = 310.65 K
- Result: 310.65 kelvin
-
Convert 0°C to kelvin:
- Start with 0°C
- Add 273.15: 0 + 273.15 = 273.15 K
- Result: 273.15 kelvin

Conversion Definitions
Celsius: Celsius is a temperature scale where 0°C is the freezing point of water and 100°C is the boiling point, under standard atmospheric conditions. It is widely used in weather forecasts, cooking, and science, providing a relative measure based on the properties of water.
Kelvin: Kelvin is the absolute temperature scale starting at absolute zero, where all molecular motion stops. It measures temperature from 0 K upward, avoiding negative numbers, and is used especially in physics and engineering to describe thermal energy.
Conversion FAQs
Can the Celsius to kelvin conversion ever produce negative values?
No, because kelvin starts at absolute zero (0 K), which equals -273.15°C. Since Kelvin cannot be below zero, any Celsius value above -273.15 will convert to a positive kelvin value.
Why is 273.15 added to Celsius to get kelvin?
The Celsius scale is relative to water’s freezing point, while kelvin scale starts at absolute zero. Adding 273.15 shifts Celsius values into kelvin by accounting for the difference between these starting points.
Is the conversion formula exact for all Celsius values?
Yes, the formula K = °C + 273.15 is exact for temperature conversion. However, practical measurements might vary slightly due to instrument precision, but the formula itself remains constant.
Can I convert kelvin back to Celsius easily?
Yes, to convert kelvin to Celsius, subtract 273.15 from the kelvin value. This reverses the original formula and gives the temperature in Celsius.
Does the conversion apply to all substances or only water?
The conversion between Celsius and kelvin only changes the temperature scale, not the physical properties of substances. It applies universally for temperature measurements regardless of the material.
