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.

The temperature scale that measures absolute temperature, created by Sir William Thomson, is known as the Kelvin scale. On this scale, absolute zero is 0 Kelvin, equivalent to -273.15 degrees Celsius.
Absolute zero on the Kelvin scale is 0 Kelvin, which is equivalent to -273.15 degrees Celsius. At this temperature, all molecular motion ceases, making it the lowest possible temperature in the universe.
Conversion formula: [K] = [°C] + 273.15 = 0 + 273.15 = 273.15 K
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
0 degrees Celsius is equivalent to 273.15 Kelvin on the Kelvin scale.
No, the Kelvin scale does not have negative temperatures. Zero Kelvin is absolute zero, the lowest temperature that can be reached where particles have minimal thermal motion. Negative temperatures do not exist on the Kelvin scale.
0 Kelvin = -273.15 degrees Celcius.
0 degrees Celsius is 273.15 Kelvin
Yes, the degree symbol is used with the Kelvin scale. For example, the temperature 0 degrees Kelvin is written as "0 K."
0 celsius is the equivalent to 273.15 Kelvin.

The temperature scale where water froze at 273 degrees is likely the Kelvin scale. On the Kelvin scale, 0 degrees represents absolute zero, the lowest possible temperature where all molecular motion ceases. Hence, 273 degrees Kelvin corresponds to 0 degrees Celsius.
The Kelvin scale is based at absolute zero. The Kelvin scale was defined when the scientist William Thomson (1st Baron Kelvin) calculated the absolute minimum thermal energy an object can have. He decided to shift the Celsius scale so that 0 would be equivalent to having zero thermal energy (aka absolute zero).
0 Degrees Kelvin, which would be Absolute Zero.
Answer: 0 ºC = 273 K
