274.15 kelvins
= 33.8 °F= 493.47 °R
equals 274.15 kelvinsFormula: K = °C + 273.15
Degree Celsius to Kelvin formula
K = °C + 273.15
Convert 5 degrees Celsius to kelvins
- Start with 5 °C.
- Apply the formula K = °C + 273.15.
- So 5 °C = 278.15 K.

Unit definitions
What is a degree Celsius?
The degree Celsius is the everyday metric temperature unit, defined so that water freezes at 0 °C and boils at 100 °C at standard pressure. It shares its degree size with the kelvin and is offset by exactly 273.15. It is the standard scale in almost every country except the United States.
What is a kelvin?
The kelvin is the SI base unit of thermodynamic temperature, redefined in 2019 via the Boltzmann constant. Its zero point is absolute zero, the coldest possible temperature, and it uses the same degree size as Celsius. It is standard in science and engineering.
Frequently asked questions
