Conversion Formula
The formula to convert Kelvin to Celsius is Celsius = Kelvin – 273.15. It works because Kelvin scale starts at absolute zero, which is -273.15 Celsius. Subtracting 273.15 adjusts the Kelvin value to Celsius, aligning the scales accordingly. For example, 100K – 273.15 = -173.15°C.
Conversion Example
- Convert 300 Kelvin to Celsius:
- Step 1: Write the formula: Celsius = Kelvin – 273.15.
- Step 2: Substitute the value: Celsius = 300 – 273.15.
- Step 3: Calculate: Celsius = 26.85.
- Result: 300 Kelvin equals 26.85 Celsius.
- Convert 150 Kelvin to Celsius:
- Step 1: Use the formula: Celsius = 150 – 273.15.
- Step 2: Calculate: Celsius = -123.15.
- Result: 150 Kelvin equals -123.15 Celsius.
- Convert 10 Kelvin to Celsius:
- Step 1: Apply the formula: Celsius = 10 – 273.15.
- Step 2: Calculate: Celsius = -263.15.
- Result: 10 Kelvin equals -263.15 Celsius.

Conversion Definitions
Kelvin: The Kelvin scale measures temperature from absolute zero, the point where particles have minimum thermal motion. It starts at 0K, with each unit equal to one degree Celsius, used mainly in scientific contexts for precise temperature measurement.
Celsius: The Celsius scale sets 0°C at the freezing point of water and 100°C at boiling point under standard conditions, based on water’s properties. It is widely used globally for everyday temperature readings and weather forecasting.
Conversion FAQs
Why is 0 Kelvin considered absolute zero?
Because at 0 Kelvin, particles reach the lowest possible energy state, with no thermal motion. This temperature marks the limit where classical physics cannot describe particle behavior, and it serves as a fundamental baseline in thermodynamics.
Can temperatures below 0 Kelvin exist in reality?
No, temperatures below 0 Kelvin are physically impossible because 0 Kelvin represents the lowest energy state. Negative Kelvin values are not meaningful in thermodynamics, although some quantum systems can have negative temperature states in specific contexts.
How accurate is the conversion from Kelvin to Celsius?
The conversion formula Kelvin minus 273.15 provides precise results within the SI system. Minor errors may occur due to measurement inaccuracies, but mathematically, the calculation is exact, assuming the Kelvin value is accurate.
What scientific instruments measure Kelvin temperatures?
Instruments like thermometers based on resistance, thermocouples, and spectrometers can measure temperatures in Kelvin, especially in laboratory or industrial settings, providing high precision for temperature-dependent experiments.
Why do scientists prefer Kelvin over Celsius?
Scientists prefer Kelvin because it starts at absolute zero, providing an absolute reference point and avoiding negative numbers. It simplifies calculations in thermodynamics and quantum physics, making temperature scales more consistent across experiments.
