First, note that Kelvin is typically not expressed in degree(s), just Temperature Kelvin
(e.g., 50 K for 50 kelvin). ***(note2 at bottom, about kelvin vs degree kelvin)
Kelvin is a temperature scale based upon 0K being absolute zero*(note1 at bottom), which is currently the lowest possible temperature. This is not possible to actually achieve, but it can be determined as the point at which a 'perfect' (ideal gas) gas would have zero pressure and volume as it contracts on cooling. As most gases behave very much like a perfect gas and the deviation of real gases is well understood, this allows us to calculate the exact temperature at which this would happen. That temperature is zero Kelvin.
For the ideal gas this is the point at which the molecules (assumed to be perfect non-interacting mathematical points) stop all motion. So the pressure (which is caused by the gas molecules bouncing off the container walls) is zero. At this point also, the gas has zero kinetic energy.
(In reality quantum mechanics shows that particles must have a certain amount of energy even at zero Kelvin. This is termed the 'zero point' energy, and is manifest in a tiny amount of vibrational energy. So in reality there is residual motion in a gas at absolute zero, but this cannot exert any pressure as that would involve removing the residual energy which cannot happen. So in quantum terms it is the point at which no mechanical energy can be extracted from the system.)
The Kelvin scale is named for British mathematician and physicist William Thompson, 1st Baron Kelvin (1824-1907), who did much to unify the modern field of Physics.

*Note1 - The Kelvin scale is indeed based upon the triple point of water, being assigned to 273.16 K; this point is beyond the scope of this discussion, however.
**Kelvin and Rankine are both based upon 0 as absolute zero, however Kelvin uses the interval of 1 K is equal to 1° Celsius, and Rankine uses the interval of 1° Rankine is equal to 1° Fahrenheit.
***Note2 - The accepted SI unit for temperature is K, not, degree(s) K. In scientific papers you will typically only find K, though it is still colloquially accepted to use degree Kelvin when you mean Kelvin.
That is called absolute zero; temperature can't go below that. At absolute zero, matter has the least possible amount of thermal energy. To convert to the common scale, just subtract 273: 0 degrees Kelvin is minus 273 degrees Celsius (Centigrade).
0 Kelvins is absolute zero, the coldest it can possibly be. It is about -273o C. When it is this cold, all motion all particles stops.
0 kelvin is Absolute Zero. This is when every particle in a sustance stops moving completely. Scientists have never reached this point yet.
0 0C = 273 Kelvin

The unit is the Kelvin. Zero on the Kelvin scale is the coldest possible temperature, absolute zero. The scale increases by the same degree intervals as the Celsius scale but since Kelvin starts at absolute zero, the values are all higher. For example, it is 273.15 K when it is 0°C (Celsius). Kelvin "K" It is KELVIN!!!!! Either Kelvin, or Celsius. Both are used with the SI K degreeskelvin
Conversion formula: [K] = [°C] + 273.15 = 0 + 273.15 = 273.15 K
Degrees in Kelvin scale = Degrees in Celsius scale + 273,15.
No, that's why it was invented. 0 on the Kelvin scale is absolute 0.
0 degrees Celsius = 273.15 kelvin.
0 degrees Celsius is 273.15 Kelvin
0 Kelvin = -273.15 degrees Celcius.
Kelvin, that's why on the Kelvin temperature scale absolute zero is 0 Kelvin and 0 degrees centigrade is 273 Kelvin.
0 celsius is the equivalent to 273.15 Kelvin.
The Kelvin scale of temperature is an absolute universale scale in SI; 0 kelvin is equal to -273,15 0C.
273
The Kelvin scale is an absolute temperature scale; 0 K corresponds to a thermodynamic temperature of absolute zero.
0 Degrees Kelvin, which would be Absolute Zero.
Answer: 0 ºC = 273 K
0 ºC = 273 K
