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: -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.

Detailed explanation-3: -Because it is an absolute scale, measurements made using the Kelvin scale do not have degrees. Thus, keeping the concept of absolute temperature in mind we may say that the Kelvin scale is better than the Celsius scale of temperature. Note: Kelvin temperature scale is considered as the SI unit of temperature.

Detailed explanation-4: -The kelvin is the same size as the Celsius degree, so measurements are easily converted from one to the other. The freezing point of water is 0°C = 273.15 K; the boiling point of water is 100°C = 373.15 K. The Kelvin and Celsius scales are related as follows: T (in °C) + 273.15 = T (in K)
