Other forms: kelvins
The kelvin is the temperature scale that starts at the coldest possible temperature. Three hundred kelvin, measured in kelvin, absolute zero.
Zero kelvin is absolute zero, about minus 273.15 degrees Celsius, where all thermal motion stops. A kelvin and a degree Celsius are the same size, so converting is only addition. There is no degree symbol and no word degrees with it: 300 kelvin, not 300 degrees kelvin. Note that colour temperature in lighting is given in kelvin, which is why a warm bulb is 2700K and daylight about 5500K.

kelvin is a unit of temperature.
