The Kelvin scale, used mainly in science and engineering, starts at absolute zero, where atomic movement stops. To convert from Celsius to Kelvin, you simply add 273.15 to the Celsius temperature.

To Kelvin's mind, absolute zero was where a temperature scale should begin, but for convenience, he used the markers and intervals of the widely-known Celsius scale as a base for his own.

Kelvin is crucial for scientific research, Celsius is widely used in everyday life around the world, and Fahrenheit remains the standard in the U.S. Understanding these scales and how to convert ...
