kelvin, abbr. K, official name in the International System of Units International System of Units, officially called the Système International d'Unités, or SI, system of units adopted by the 11th General Conference on Weights and Measures (1960). It is based on the metric system . ..... Click the link for more information. (SI) for the degree of temperature as measured on the Kelvin temperature scale Kelvin temperature scale, a temperature scale having an absolute zero below which temperatures do not exist. Absolute zero , or 0°K;, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of −273. ..... Click the link for more information. . KelvinA unit of measurement of temperature. Part of the SI system of measurement, the Kelvin (K) scale starts at absolute zero (-273.15). Each Kelvin degree is the same as a Celsius degree. As a result, 0ºC (freezing water) is equal to 273.15K, and 100ºC (boiling water) is equal to 373.15K. From British physicist and mathematician Lord William Thomas Kelvin (1824-1907). See SI. kelvin the basic SI unit of thermodynamic temperature; the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. Kelvin William Thomson, 1st Baron Kelvin. 1824--1907, British physicist, noted for his work in thermodynamics, inventing the Kelvin scale, and in electricity, pioneering undersea telegraphy How to thank TFD for its existence?

A cooler on Suzaku keeps the detector at temperatures low enough to sense the tiny amount of heat imparted by an individual X-ray photon--just a few thousandths of a degree kelvin. As such, Brijot has achieved a total system-level sensitivity that can distinguish a one degree Kelvin (1 degree K) difference in millimeter wave signatures. |
