What is Kelvin?

Definition:

The kelvin is the base unit of temperature in the International System of Units (SI).

The kelvin scale is a thermodynamic (absolute) temperature scale, named after the famous engineer and physicist William Thomson, 1st Baron Kelvin (1824-1907). The kelvin scale is defined by absolute zero and the triple point of water. The absolute zero (0 K) is the temperature at which the thermal motion of the particles ceases to exist in the classical description of thermodynamics. The triple point of water is the combination of temperature and pressure at which all three phases of water (liquid water, solid ice and water vapour) coexist in thermodynamic equilibrium. The triple point of water occurs at a temperature of 273.16 K and a partial vapour pressure of 611.73 pascals (0.0060373 atm). On the kelvin temperature scale, the freezing point of water corresponds to 273.15 K and the boiling point of water corresponds to 373.15 K at normal pressure (1 atmosphere).

Common temperature conversions:

  • 0 kelvins (K) = -273.15 degrees Celsius (°C) or centigrade = -459.67 degrees Fahrenheit (°F)
  • 273.15 kelvins (K) = 0 degrees Celsius (°C) or centigrade = 32 degrees Fahrenheit (°F)
  • 293.15 kelvins (K) = 20 degrees Celsius (°C) or centigrade = 68 degrees Fahrenheit (°F)
  • 373.15 kelvins (K) = 100 degrees Celsius (°C) or centigrade = 212 degrees Fahrenheit (°F)
