Conversion formula: °C = K − 273.15 and kelvin = 273.15 + Celsius. Absolute zero temperature: 0 K = 273.15 °C (degrees Celsius). The K (kelvin) is a unit of temperature and one of the units of International System of Units (SI). The Kelvin temperature scale is an absolute scale where zero K is an absolute absence of any thermal energy. The kelvin (K) unit is named after the British scientist William Thomson (lived 1824–1907), who developed the absolute temperature scale, named after him. Please note that kelvin (K) is not referred to as a "degree", and written without degree symbol (°).
Sample conversion: we need to convert 1°C to kelvin  the conversion formula is going to be kelvin = 273.15 + 1°Celsius. After the calculator is used we will get the result : 274.15 K.
