Quick Answer:
K = °C + 273.15. To convert Celsius to Kelvin, add 273.15 to the Celsius value.
Celsius and Kelvin are the standard temperature units in science, physics, and chemistry.
Detailed Overview: Celsius to Kelvin
The Celsius scale sets 0°C at water’s freezing point. The Kelvin scale is the SI base unit of temperature and starts at absolute zero. K = °C + 273.15. To convert Kelvin to Celsius, subtract 273.15. Used in physics, chemistry, and engineering. Absolute zero is 0 K or -273.15°C.
Conversion Reference Table
-273.15°C = 0 K, 0°C = 273.15 K, 25°C = 298.15 K, 37°C = 310.15 K, 100°C = 373.15 K, 1000°C = 1273.15 K
Practical Calculation Example
Convert 50°C: K = 50 + 273.15 = 323.15 K. Reverse: 400 K = 400 – 273.15 = 126.85°C
Key Takeaways
K = °C + 273.15. To convert Celsius to Kelvin, add 273.15. To convert Kelvin to Celsius, subtract 273.15.
THE AUTORANK Editorial Note: In scientific calculations, always use Kelvin for gas law equations because they require absolute temperature.
