The kelvin (symbol: K) is an absolute thermodynamic temperature measurement scale. As such it is also part of the International Standards (SI) base units.

It is important to note that the Kelvin scale is based on 2 reference points:
1. The kelvin scale relies on the Absolute Zero, which is the temperature at which ALL kinetic motion of matter particles stops.

2. And its second point of reference is the triple point of pure water (prepared as per the VSMOW* standard). The triple point of pure water is defined as the point of temperature and atmospheric pressure at which the three phases of the substance (gas, liquid & solid) can coexist.

Kelvin temperature scale, a temperature scale having an absolute zero below which temperatures do not exist. Absolute zero, or 0K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of -273.15° on the Celsius temperature scale. The Kelvin degree is the same size as the Celsius degree; hence the two reference temperatures for Celsius, the freezing point of water (0°C), and the boiling point of water (100°C), correspond to 273.15K and 373.15K, respectively. When writing temperatures in the Kelvin scale, it is the convention to omit the degree symbol and merely use the letter K. The temperature scale is named after the British mathematician and physicist William Thomson Kelvin, who proposed it in 1848. Another absolute temperature scale, the Rankine temperature scale, is used by some engineers. You'll find more good science information at http://www.mysciencebuzz.com

It's a measure of temperature, like Celsius (centigrades) and Fahrenheit.

The zero point of the Kelvin scale is the absolute zero point, that is the temperature when all atoms are lying still. This is more convenient for calculations than the somewhat arbitrary zero points of the other scales. Therefore, scientists usually prefer to work with the Kelvin scale.

Absolute temperature

Absolute because it is based on absolute zero, the temperature at which, all molecular movement cease.

Its named after Lord Kelvin, a groovy science guy.

Answers above are correct, but I would add one thing:
We say 27 degrees C.
We say 32 degrees farenheit
but we just say 320 Kelvin (NOT the word degree)

Kevin or K, in science stands for that stupidest KID in science class.
