Kelvin is the name given to the basic thermodynamic temperature unit, according to the International System of Units.
The temperature of 1 Kelvin corresponds to -272.15°C (celsius) and -457.87°F (Fahrenheit). On the Kelvin scale, for example, 273.15 Kelvin equals 0 degrees Celsius and 32 Fahrenheit.
Furthermore, 0º K indicates the absolute zero, a situation where there is a temperature of -273.15 °C or -459.67 °F. Absolute zero is a theoretical concept that indicates the lowest temperature that can be verified in the Universe. Under these conditions the kinetic energy of the molecules is canceled out, and they become immobile.
This scale is named after Lord Kelvin, a title attributed to William Thomson, an Irish-born physicist. The work of this British scientist was of high importance, being used to manufacture electrical cables and galvanometers. In addition, Lord Kelvin was also involved in the installation of the telephone system in Great Britain. The title of nobility received at the age of 68 was an acknowledgment of his work.
There are several websites that offer conversion tools between Kelvin, Fahrenheit and Celsius, the three most popular temperature scales.
