Celsius to Kelvin

Celsius to Kelvin uses K = C + 273.15. The inverse relationship for Celsius to Kelvin is C = K − 273.15.

Celsius to Kelvin input definition: degrees Celsius use the scale where absolute zero is −273.15 °C. For Celsius to Kelvin, output definition: kelvin is the SI base unit of thermodynamic temperature; 0 K is absolute zero.

Celsius to Kelvin check: 0 Celsius = 273.15 Kelvin. Celsius to Kelvin check: 20 Celsius = 293.15 Kelvin. Celsius to Kelvin check: 100 Celsius = 373.15 Kelvin.

Formula: Kelvin = Celsius + 273.15. Common checks help catch mistakes: freezing water is 0 Celsius or 32 Fahrenheit, room temperature is around 20 to 25 Celsius, and boiling water is around 100 Celsius at sea level. Use these reference points when the kelvin result will be used for weather, cooking, science homework, equipment settings, or travel planning.

Common checks: freezing water is 0 Celsius or 32 Fahrenheit, room temperature is around 20 to 25 Celsius, and boiling water is around 100 Celsius at sea level.
