Quick Answer:
°C = K – 273.15. To convert Kelvin to Celsius, subtract 273.15 from the Kelvin value.
Kelvin and Celsius are the standard temperature units in science, physics, and chemistry.
Detailed Overview: Kelvin to Celsius
The Kelvin scale is the SI base unit of temperature and starts at absolute zero. The Celsius scale sets 0°C at water’s freezing point. °C = K – 273.15. To convert Celsius to Kelvin, add 273.15. Used in physics, chemistry, and engineering. Absolute zero is 0 K or -273.15°C.
Conversion Reference Table
0 K = -273.15°C, 100 K = -173.15°C, 273.15 K = 0°C, 298.15 K = 25°C, 310.15 K = 37°C, 373.15 K = 100°C
Practical Calculation Example
Convert 350 K: °C = 350 – 273.15 = 76.85°C. Reverse: 200°C = 200 + 273.15 = 473.15 K
Key Takeaways
°C = K – 273.15. To convert Kelvin to Celsius, subtract 273.15. To convert Celsius to Kelvin, add 273.15.
THE AUTORANK Editorial Note: Kelvin is never written with a degree symbol, while Celsius and Fahrenheit always use one.
