About this conversion
Convert Celsius to Kelvin for science classes, chemistry, physics, climate data, and engineering formulas.
Celsius is a practical temperature scale based on water freezing at 0 °C and boiling near 100 °C at standard pressure.
Kelvin is the SI thermodynamic temperature scale and starts at absolute zero.
Typical uses
- Thermodynamics and gas-law calculations
- Scientific data normalization
- Engineering formulas that require absolute temperature
Common reference values
- 1 °C = 274.15 K
- 10 °C = 283.15 K
- 100 °C = 373.15 K
Tip: Add 273.15 to Celsius to get Kelvin. Example: 25 °C = 298.15 K.
Educational reference - always verify critical measurements (medical, engineering, legal) with primary sources.
