Kelvin scale

The temperature scale used in physics, synonym: absolute temperature.

The zero point of the Kelvin scale is at absolute zero; a temperature difference of one Kelvin (abbreviated 1 K and, rarely, also called one “degree Kelvin”) is the same as a temperature difference of one degree Celsius, as both scales differ only by their choice of zero point: X degrees Celsius are (X plus 273.15) Kelvin, Y Kelvin are (Y minus 273,15) degrees Celsius.

Relation to the Fahrenheit scale: X degrees Fahrenheit are (X+459,67)*5/9 Kelvin, Y Kelvin are (Y*9/5)-459,67 degrees Fahrenheit.
