Kelvin vs. Fahrenheit — What's the Difference?

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 1.380649×10−23 J⋅K−1.

The Fahrenheit scale ( or ) is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit.

A unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water. One kelvin degree is equal to one Celsius degree. See Table at measurement.

Of or relating to a temperature scale that registers the freezing point of water as 32° and the boiling point as 212° at one atmosphere of pressure. See Table at measurement.

Kelvin A temperature scale in which zero occurs at absolute zero and each degree equals one kelvin. Water freezes at 273.15 K and boils at 373.15 K.

Conforming to the scale used by Gabriel Daniel Fahrenheit in the graduation of his thermometer; of or relating to Fahrenheit's thermometric scale. Used as an alternative to celsius.

In the International System of Units, the base unit of thermodynamic temperature; 273.16 of the thermodynamic temperature of the triple point of water. Shown as "K".

German physicist who invented the mercury thermometer and developed the scale of temperature that bears his name (1686-1736)

A unit interval on the Kelvin scale.

(usually as postpositioned adjective) A unit for a specific temperature on the Kelvin scale.

The SI unit of temperature, defined as being 1/273.16 of the triple point of water; abbreviated K. The melting point of water at 760 mm pressure is 273.15 Kelvins, and the boiling point 373.15 Kelvins. One degree Kelvin is equal to one degree Centigrade, and
