Kelvin scale was developed by Lord kelvin ( William Thomson ) in 1848. Lord Kelvin developed this scale with the help of

*Carnot engine*. Kelvin is a unit of measurement of temperature. It is the one of the seven base units in the International system of units ( SI ). The Kelvin symbol K is the SI unit of temperature. It is defined as the fraction 1/273.16 of the thermodynamic ( absolute ) temperature of the triple point of water.The zero point of this scale is equivalent to Celsius scale. This zero point is considered the lowest possible temperature of anything in the universe. Therefore, the kelvin scale is also known as*"absolute scale".*- Freezing point of water, kelvin scale reads to 273 K.
- Boiling point of water, it reads to 373 K.
