The kelvin now only depends on the Boltzmann constant and universal constants (see 2019 SI unit dependencies diagram), allowing the kelvin to be expressed as: [2] 1 kelvin = 1.380 649 × 10 −23 / (6.626 070 15 × 10 −34)(9 192 631 770) h Δν Cs / k B ≈ 2.266 6653 h Δν Cs / k B .
This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...
This means that a temperature difference of one degree Celsius and that of one kelvin are exactly the same. On 20 May 2019, the kelvin was redefined so that its value is now determined by the definition of the Boltzmann constant rather than being defined by the triple point of VSMOW. This means that the triple point is now a measured value, not ...
De color gris aparecen las temperaturas que sirvieron históricamente para la definición de la magnitud de un grado Celsius: los puntos de congelamiento (0.00 °C, 273.15 K) y ebullición del agua (100 °C, 373.15 K). Se puede apreciar que ambas escalas, tanto la Celsius como la Kelvin tienen unidades de la misma magnitud.
Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...

Zero kelvin (−273.15 °C) is defined as absolute zero.. Absolute zero is the lowest limit of the thermodynamic temperature scale; a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value.
Joseph-Nicolas Delisle. The Delisle scale is a temperature scale invented in 1732 by the French astronomer Joseph-Nicolas Delisle (1688–1768). [1] The Delisle scale is notable as one of the few temperature scales that are inverted from the amount of thermal energy they measure; unlike most other temperature scales, higher measurements in degrees Delisle are colder, while lower measurements ...
