Kelvin and Celsius are two different temperature scales. The size of degree for both the scale is same in magnitude but the Kelvin scale gets initiated at absolute zero, while the Celsius scale sets its initial point at the triple point of water. The particulate equation to convert Kelvin in Celsius is, K = °C + 273.15. Hence, 25 °C when converted into kelvin is done with the following equation.

K = °C + 273.15 = 25 + 273.15 = 298.15.

Celsius and Kelvin are the two most significant temperature scales for the scientific measurements. Fortunately, its pretty easy to convert between them since the two scales have the same size of the degree. All the requirements which is needed for the process of conversion between the two temperature scales is a single simple step.

During the process of the conversion, 273.15 is needed to be added to the Celsius temperature and the answer of the equation will be in kelvin. A reminder regarding the implementation is that the kelvin temperature does not use the degree symbol. The reason behind this is that the kelvin is an absolute scale based on the function of absolute zero. On the other hand, the Celsius scale is dependent on the properties which water possesses.

We make use of the number 273 to convert from Celsius to Kelvin and vice versa. In Kelvin temperature scale, the shifting of the zero point from the freezing point of water to the point of absolute zero. Absolute zero is theoretically the most lowest temperature which is achieved by a substance, and hence there is a need of conversion from Celsius to Kelvin for the temperature value.
