28 degrees Celsius is equal to 301.15 Kelvin.
To convert Celsius to Kelvin, you add 273.15 to the Celsius temperature. This is because the Kelvin scale starts at absolute zero, which is -273.15°C, so shifting the scale by 273.15 aligns the two temperature scales.

Conversion Formula
The formula to convert Celsius (°C) to Kelvin (K) is:
K = °C + 273.15
This formula works because the Kelvin scale is shifted from Celsius by 273.15, representing absolute zero. Since Kelvin starts at 0 K which equals -273.15°C, adding 273.15 to any Celsius value moves it into the Kelvin scale.
Example calculation:
- Given: 28°C
- Add 273.15: 28 + 273.15 = 301.15 K
- So, 28°C equals 301.15 K.
Conversion Example
- Convert 15°C to Kelvin:
- Start with 15°C.
- Add 273.15: 15 + 273.15 = 288.15 K.
- Result: 15°C = 288.15 K.
- Convert -10°C to Kelvin:
- Start with -10°C.
- Add 273.15: -10 + 273.15 = 263.15 K.
- Result: -10°C = 263.15 K.
- Convert 0°C to Kelvin:
- Start with 0°C.
- Add 273.15: 0 + 273.15 = 273.15 K.
- Result: 0°C = 273.15 K.
- Convert 50°C to Kelvin:
- Start with 50°C.
- Add 273.15: 50 + 273.15 = 323.15 K.
- Result: 50°C = 323.15 K.

Conversion Definitions
Celsius: Celsius is a temperature scale where water freezes at 0 degrees and boils at 100 degrees under standard atmospheric pressure. The scale is used worldwide for measuring temperature in weather, cooking, and science, and is based on the metric system.
Kelvin: Kelvin is an absolute temperature scale starting at absolute zero, the coldest possible temperature where particles have minimum energy. Kelvin is used in scientific measurements and thermodynamics, with no negative values since it begins at zero.
Conversion FAQs
Why do we add 273.15 when converting Celsius to Kelvin?
We add 273.15 because the Kelvin scale starts at absolute zero, which is -273.15°C. Adding this value shifts the Celsius temperature upward so it fits onto the Kelvin scale, which starts at zero and has no negative numbers.
Can Kelvin values be negative like Celsius?
No, Kelvin temperatures cannot be negative. Since the Kelvin scale begins at absolute zero, the lowest temperature possible, all Kelvin values are zero or positive. Negative Kelvin would imply a temperature below absolute zero, which is physically impossible.
Is the conversion from Celsius to Kelvin affected by pressure or altitude?
The conversion formula itself is not affected by pressure or altitude because it’s just a scale shift. However, actual temperature readings can vary with atmospheric conditions, but converting between Celsius and Kelvin uses a fixed numeric offset.
How precise is the conversion factor 273.15?
The value 273.15 is defined exactly by the international temperature scale and is precise enough for most scientific and practical purposes. Slight variations in real-world measurements happen due to environmental factors, but 273.15 is the accepted constant.
Can I convert Kelvin back to Celsius easily?
Yes, converting Kelvin to Celsius is done by subtracting 273.15 from the Kelvin value. This reverses the original conversion, moving the temperature back to the Celsius scale.
