65 degrees Celsius equals 338.15 kelvin.
To convert Celsius to kelvin, you add 273.15 to the Celsius temperature. This shifts the scale from relative to absolute zero, so 0°C becomes 273.15 K, reflecting the absolute temperature.

Conversion Formula
The formula to convert Celsius (°C) to kelvin (K) is:
K = °C + 273.15
This works because Celsius scale is based on water freezing and boiling points, while kelvin is an absolute scale starting at absolute zero (-273.15°C). Adding 273.15 shifts the temperature to kelvin.
Example:
- Given temperature: 65°C
- Add 273.15: 65 + 273.15 = 338.15 K
- So, 65 degrees Celsius equals 338.15 kelvin.
Conversion Example
- Convert 20°C to kelvin:
- Start with 20°C.
- Add 273.15: 20 + 273.15 = 293.15 K.
- Result: 293.15 kelvin.
- Convert -10°C to kelvin:
- Take -10°C.
- Add 273.15: -10 + 273.15 = 263.15 K.
- Result: 263.15 kelvin.
- Convert 0°C to kelvin:
- 0 plus 273.15 equals 273.15 K.
- So, 0°C equals 273.15 kelvin.
- Convert 100°C to kelvin:
- Adding 273.15 to 100 gives 373.15 K.
- So, 100°C is 373.15 kelvin.
- Convert 50.5°C to kelvin:
- 50.5 + 273.15 = 323.65 K.
- This means 50.5°C equals 323.65 kelvin.

Conversion Definitions
Celsius: Celsius is a temperature scale based on 0°C as freezing point of water and 100°C as boiling point under standard atmospheric pressure. It is widely used for everyday temperature measurements, its scale is relative and centered around water’s phase changes.
Kelvin: Kelvin is an absolute temperature scale starting at absolute zero, the lowest possible temperature where particles have minimum thermal motion. It is used in science and engineering, with 0 K equivalent to -273.15°C, and increments equal to Celsius degrees.
Conversion FAQs
Can Celsius values be negative when converting to kelvin?
Yes, Celsius values below zero will result in kelvin values above zero because kelvin starts at absolute zero. For example, -10°C converts to 263.15 K by adding 273.15, so kelvin values never drop below zero.
Why is the number 273.15 used in the conversion?
273.15 represents the offset between the zero points of Celsius and kelvin scales. Absolute zero is -273.15°C, so adding 273.15 shifts the temperature to the kelvin scale, ensuring no negative values exist in kelvin.
Is the conversion formula exact for all temperatures?
The formula K = °C + 273.15 is exact for converting between Celsius and kelvin in practical terms. Minor differences may exist in thermodynamic calculations at extreme conditions, but it serves perfectly for general use.
Can I convert kelvin back to Celsius easily?
Yes, converting kelvin to Celsius is simply subtracting 273.15 from the kelvin value. For example, 338.15 K minus 273.15 equals 65°C, reversing the conversion.
Does this conversion apply to Fahrenheit temperatures?
No, Fahrenheit uses a different scale. To convert Fahrenheit to kelvin requires first converting Fahrenheit to Celsius, then adding 273.15. Direct Fahrenheit to kelvin conversion needs more complex formulas.
