Detailed explanation-1: -The kelvin is the SI unit of thermodynamic temperature, and one of the seven SI base units . Unusually in the SI, we also define another unit of temperature, called the degree Celsius (°C). Temperature in degrees Celsius is obtained by subtracting 273.15 from the numerical value of the temperature expressed in kelvin.

Detailed explanation-2: -The kelvin, symbol K, is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 x 10–23 when expressed in the unit J K–1, which is equal to kg m2 s–2 K–1, where the kilogram, metre and second are defined in terms of h, c and Cs.

Detailed explanation-3: -The SI unit of temperature as per the International System of Units is Kelvin which is represented by the symbol K. The Kelvin scale is widely accepted or used in the field of science and engineering.

Detailed explanation-4: -The kelvin, symbol K, is the primary unit of temperature in the International System of Units (SI), used alongside its prefixed forms and the degree Celsius.

Detailed explanation-5: -Each division in the kelvin scale called a kelvin (K) is equal to a degree on the Celsius scale, but the difference is where zero is. In the Celsius scale 0o is the freezing point of water while in the Kelvin scale the zero point is at absolute zero. Therefore, 0oK is equal to-273.15oC, 0oC is equal to 273.15 kelvins.
