Convert fahrenheit to kelvin
Fahrenheit
The Fahrenheit scale (fɑːr>ənhaɪt) is a temperature scale based on one proposed in 1724 by physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist. The lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from equal parts of ice, water and a salt (ammonium chloride). Further limits were established as the freezing point of ice (32 °F) and his best estimate of the average human body temperature (96 °F, about 2.6 °F less than the modern value due to a later redefinition of the scale). The scale is now usually defined by two fixed points: the temperature at which water freezes into ice is defined as 32 °F, and the boiling point of water is defined to be 212 °F, a 180 °F separation, as defined at sea level and standard atmospheric pressure.
Kelvin
The kelvin is the base unit of 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).
One kelvin is equal to a change in the thermodynamic temperature T that results in a change of thermal energy by 1.380 649×10 −23 J.
