Organizing and summarizing search results for youThe Kelvin temperature scale was invented by Lord Kelvin in 1848. The scale measures the ultimate extremes of hot and cold, and is based on the idea of absolute temperature. In 1954, the General Conference on Weights and Measures adopted the kelvin (K) as the base unit for thermodynamic temperature, making it the preferred scale for scientists.2 SourcesKelvin: History | NIST

Kelvin - Wikipedia
During the 18th century, multiple temperature scales were developed, notably Fahrenheit and centigrade (later Celsius). These scales predated much of the modern science of thermodynamics, including atomic theory and the kinetic theory of gases which underpin the concept of absolute zero. Instead, they chose defining points within the range of human experience that could be reproduce…

Kelvin - New World Encyclopedia
- By international agreement, the unit “kelvin” and its scale are defined by two points: Absolute zero, and the triple point of specially prepared (VSMOW) water. This definition also precisely relates the Kelvin scale to the Celsius scale. Absolute zero—the temperature at which nothing could be colder and no heat energy remains in a substance—is defi...
