Convert Celsius to Kelvin (°C to K)
Instant precision conversion from Celsius (°C) to Kelvin (K) in Temperature.
⚡ Direct Answer: 1 °C to K
1 °C corresponds to 274.15 K (the kelvin and degree Celsius have the same interval size, with 0 °C corresponding to 273.15 K).
To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.
📐 How Celsius (°C) and Kelvin (K) Relate
In metrology, temperature quantifies thermodynamic temperature and kinetic molecular energy. Within this domain, Celsius (°C) and Kelvin (K) originate from Celsius (°C), Fahrenheit (°F), Kelvin (K), Rankine (°R), and Réaumur (°Re). The kelvin and degree Celsius share the same unit interval size under SI definitions, with 0 °C corresponding to 273.15 K.
Unlike purely proportional units, temperature scales differ in both their degree intervals and their zero-point reference baselines. Converting between Celsius and Kelvin requires an affine transformation (K = °C + 273.15) that shifts the temperature offset before scaling the unit intervals.
