Conversion Formula
To convert degree Celsius to kelvin, you add 273.15 to the Celsius value. The kelvin scale starts at absolute zero, which is -273.15°C. By adding this number, you shift the Celsius temperature into the kelvin scale which measures thermal energy absolutely.
Formula:
K = °C + 273.15
For example:
If the temperature is 1°C, then
K = 1 + 273.15 = 274.15 kelvin.
Conversion Example
- Convert 10°C to kelvin:
- Start with 10°C.
- Add 273.15 to 10.
- 10 + 273.15 = 283.15 K.
- Convert -5°C to kelvin:
- Start with -5°C.
- Add 273.15 to -5.
- -5 + 273.15 = 268.15 K.
- Convert 20.5°C to kelvin:
- Start with 20.5°C.
- Add 273.15 to 20.5.
- 20.5 + 273.15 = 293.65 K.
- Convert -10°C to kelvin:
- Start with -10°C.
- Add 273.15 to -10.
- -10 + 273.15 = 263.15 K.

Conversion Definitions
Degree (Celsius): Degree Celsius is a temperature unit, measuring how hot or cold something is relative to water’s freezing and boiling points. Zero degrees Celsius is the freezing point of water, and 100 degrees Celsius is the boiling point under standard pressure. It is widely used in everyday temperature measurements.
Kelvin: Kelvin is the base unit of temperature in the International System, starting at absolute zero where particles have minimum thermal motion. Unlike Celsius, kelvin has no negative values and is used in scientific fields to measure temperatures above absolute zero, essential for thermodynamics and physics calculations.
Conversion FAQs
Can temperature in degree Celsius be negative in kelvin?
No, kelvin scale starts at absolute zero (0 K), so kelvin values cannot be negative. Even if Celsius temperature is below zero, when converted to kelvin by adding 273.15, the result is always positive or zero.
Why add 273.15 to convert Celsius to kelvin?
The kelvin scale begins at absolute zero, which corresponds to -273.15°C. Adding 273.15 shifts the Celsius scale to start at absolute zero, aligning the two scales properly for scientific use.
Is kelvin used outside scientific research?
Kelvin is mostly used in scientific and engineering fields, but rarely in daily life since Celsius or Fahrenheit are more intuitive for weather and cooking temperatures. Kelvin is critical when precise absolute temperature measurements are required.
Can I convert kelvin back to Celsius?
Yes, subtract 273.15 from kelvin temperature to get degrees Celsius. For example, 300 K minus 273.15 equals 26.85°C.
Does converting Celsius to kelvin affect physical properties?
Converting units doesn’t change the physical temperature itself, only how it’s expressed. The actual thermal energy remains the same, only the numeric representation changes based on the scale.
