25 Celsius is equal to 298.15 Kelvin.
The conversion from Celsius to Kelvin is done by adding 273.15 to the Celsius temperature. This shifts the scale so that absolute zero, the lowest possible temperature, is at 0 Kelvin. Therefore, 25 degrees Celsius plus 273.15 gives 298.15 Kelvin.

Conversion Formula
The formula to convert Celsius (°C) to Kelvin (K) is:
K = °C + 273.15
This formula adds 273.15 to the Celsius temperature to shift the scale from the freezing point of water (0 °C) to absolute zero (0 K). The Kelvin scale starts at absolute zero, which is the lowest temperature possible, where molecular motion nearly stops.
Example: Convert 25 °C to Kelvin.
- Start with the Celsius temperature: 25 °C
- Add 273.15 to it: 25 + 273.15 = 298.15
- The result is 298.15 K
Conversion Example
- Convert 10 °C to Kelvin:
- Take 10 and add 273.15
- 10 + 273.15 = 283.15 K
- Final answer: 283.15 Kelvin
- Convert -5 °C to Kelvin:
- Start with -5
- Add 273.15: -5 + 273.15 = 268.15
- Kelvin value: 268.15 K
- Convert 37 °C to Kelvin:
- 37 plus 273.15 equals 310.15
- Therefore, 310.15 K is the temperature in Kelvin
- Convert 0 °C to Kelvin:
- Adding 273.15 to zero gives 273.15 K
- This is the freezing point of water in Kelvin

Conversion Definitions
Celsius: Celsius is a temperature scale where zero degrees is the freezing point of water and one hundred degrees is the boiling point under standard atmospheric pressure. It’s widely used in everyday temperature measurements across the world, except in a few countries.
Kelvin: Kelvin is the SI base unit for temperature, starting at absolute zero, the lowest physical temperature possible. Unlike Celsius, Kelvin does not use degrees and is mainly used in science and engineering for precise temperature measurements.
Conversion FAQs
Is the Kelvin scale always higher than Celsius for any temperature?
Yes, since Kelvin starts at absolute zero (-273.15°C), its values are always 273.15 units higher than Celsius. So, a Celsius value added by 273.15 gives the Kelvin equivalent, meaning Kelvin values will always be greater than or equal to Celsius values.
Do I need to consider negative values when converting Celsius to Kelvin?
Yes, negative Celsius values are valid and converting them to Kelvin is done by the same formula. However, the result in Kelvin must not be below zero, since negative Kelvin values do not exist in physics.
Why is 273.15 added in the conversion formula?
273.15 is the temperature difference between absolute zero and the freezing point of water on the Celsius scale. Adding this offset shifts the Celsius scale so zero Kelvin equals absolute zero.
Can Kelvin be converted back to Celsius easily?
Yes, converting Kelvin to Celsius involves subtracting 273.15 from the Kelvin value. This reverses the offset, giving the temperature on Celsius scale.
Is Kelvin used in weather forecasts instead of Celsius?
No, weather forecasts mostly use Celsius or Fahrenheit. Kelvin is used mainly in scientific fields like physics and astronomy where absolute temperature measurements are required.
