1. Kelvin

   The kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. It is named after the Belfast-born, Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907). 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. 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. One kelvin is equal to a change in the thermodynamic temperature T that results in a change of thermal energy kT by 1.380 649×10−23 J.The Kelvin scale fulfills Thomson's requirements as an absolute thermodynamic temperature scale. It uses absolute zero as its null point. Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or written as a degree. The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude.

1. kelvin

   Kelvin is the base unit of temperature in the International System of Units (SI). It is defined by setting the thermodynamic temperature of the triple point of water as exactly 273.16 kelvins. Unlike degrees Celsius or Fahrenheit, Kelvin is not measured in degrees and does not use any type of degree symbol. The Kelvin scale is an absolute temperature scale starting at absolute zero, the theoretical lowest temperature possible.

1. Kelvin

   The kelvin is a unit of measurement for temperature. It is one of the seven base units in the International System of Units and is assigned the unit symbol K. The Kelvin scale is an absolute, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The kelvin is defined as the fraction ¹⁄273.16 of the thermodynamic temperature of the triple point of water. The Kelvin scale is named after the Belfast-born, Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin, who wrote of the need for an "absolute thermometric scale". Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or typeset as a degree. The kelvin is the primary unit of measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Subtracting 273.16 K from the temperature of the triple point of water makes absolute zero equivalent to −273.15 °C.

Examples of kelvin in a Sentence

1. Kelvin Throop:

   Ancient man believed there were four states of matter: Earth, Wind, Water, and Fire. Today, modern science has proven there are actually four states of matter: Solid, Gas, Liquid, and Plasma. Thank God for progress.” -Kelvin R. Throop III

2. Harvey Fineberg:

   That's the brilliance of Kelvin Droegemeier, to elicit this kind of input and turn to the academics in the first place, they're genuinely trying to widen their aperture for advice, and I think so far it's working.

3. Kelvin III Throop:

   I have never seen a problem so convoluted and complex, that when looked at in just the right angle, didn’t somehow seem more convoluted and complex.” -Kelvin R. Throop III

4. Mario Damasso:

   Not habitable at all, I would say, since we predict with back of the envelope calculation its temperature to be around 40 Kelvin, we have no clue on the actual planet structure and composition, although we can likely imagine that it has an extended atmosphere made mostly of [hydrogen]and [helium].
