The kelvin is the base unit of temperature in the International System of Units, having the unit symbol K. It is named after the Belfast-born, Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin. The kelvin is now defined by fixing the numerical value of the Boltzmann constant k to 1.380 649×10⁻²³ J⋅K⁻¹. This unit is equal to kg⋅m²⋅s⁻²⋅K⁻¹, where the kilogram, metre and second are defined in terms of the Planck constant, the speed of light, and the duration of the caesium-133 ground-state hyperfine transition respectively. Thus, this definition depends only on universal constants, and not on any physical artifacts as practiced previously, such as the International Prototype of the Kilogram, whose mass diverged over time from the original value.

  • International Temperature Scale of 1990 - The International Temperature Scale of 1990 published by the Consultative Committee for Thermometry of the International Committee for Weights and Measures is an equipment calibration standard for making measurements on the Kelvin and Celsius temperature scales.
  • Negative temperature - Certain systems can achieve negative temperature; that is, their temperature can be expressed as a negative quantity on the Kelvin or Rankine scales. The absolute temperature scale can be understood loosely as a measure of average kinetic energy. Usually, system temperatures are positive.
