The result of converting 4 c to kelvin is 277.15 kelvin.
To change 4 c into kelvin, you add 273.15 to the celsius temperature. This is because kelvin starts at absolute zero, making the zero point different than celsius. The calculation for 4 c is therefore: 4 + 273.15 = 277.15 kelvin. This method works for any celsius value, not just 4.

Conversion Formula
The formula for converting c to kelvin is simple: K = °C + 273.15. Celsius and kelvin scales are both based on divisions of 100, but kelvin starts at the lowest possible temperature, which celsius calls -273.15°C. So, by adding 273.15 you shift the scale to start at absolute zero.
Here’s how it works:
- Write down your temperature in c. Let’s say it’s 4.
- Add 273.15 to this number: 4 + 273.15 = 277.15
- The answer, 277.15, is the temperature in kelvin.
Another example, if you have -10 c: -10 + 273.15 = 263.15 kelvin.
Conversion Example
- Convert 15 c to kelvin:
- Start with 15.
- Add 273.15: 15 + 273.15 = 288.15
- Result: 288.15 kelvin
- Convert -5 c to kelvin:
- Begin with -5.
- Add 273.15: -5 + 273.15 = 268.15
- Result: 268.15 kelvin
- Convert 0 c to kelvin:
- Start at 0 c.
- Add 273.15: 0 + 273.15 = 273.15
- Result: 273.15 kelvin
- Convert 29 c to kelvin:
- Start with 29.
- Add 273.15: 29 + 273.15 = 302.15
- Result: 302.15 kelvin
- Convert -21 c to kelvin:
- Begin at -21.
- Add 273.15: -21 + 273.15 = 252.15
- Result: 252.15 kelvin
Conversion Chart
Below is a conversion chart for c values from -21.0 to 29.0, showing their corresponding kelvin measurements. Each row adds the same 273.15 to the celsius value. Use it by finding your c value in the left column, then reading the kelvin value to the right—it works for any value in this range.

Conversion Definitions
c: c stands for celsius, a temperature scale where 0° is freezing point for water and 100° is boiling. Used in most countries for weather and science, it’s based on the metric system. Celsius measures thermal energy but isn’t absolute, so negative values exist.
kelvin: kelvin is the SI unit for absolute temperature. It starts at absolute zero, the coldest possible temperature where molecules have minimum energy. There are no negative kelvin values. Each kelvin unit is equal in size to a degree celsius, but the scale begins at 0 K, not at freezing water.
Conversion FAQs
Do you need to change the decimal part when converting from c to kelvin?
No, the decimal part just carries over. For instance, 4.5 c becomes 4.5 + 273.15 = 277.65 kelvin. Decimal accuracy depends on your starting value, so if you had 4.01 c, it would be 277.16 kelvin if rounded up at two decimals. Don’t drop decimals unless instructed.
Why does kelvin not have a degree symbol?
Kelvin is an absolute scale, so it does not use the degree symbol. Unlike celsius or fahrenheit, kelvin is a physical measurement of energy, so it’s written as just K, not °K, to avoid confusion between types of temperature scales.
Can you get a negative kelvin reading if c is below -273.15?
No, you cannot. The lowest possible celsius temperature is -273.15°C, which equals 0 kelvin. If you plug in a lower c value, the math would give a negative kelvin, but this doesn’t exist in real physical systems, so it’s not possible in practice.
Is the conversion from c to kelvin linear?
Yes, it’s a straight linear relationship. Every change of 1 c equals the same change of 1 kelvin. Only the zero points is different between the two scales, but the size of each step is identical, so you can convert back and forth easily.
