WebAbsolute zero is 0 Kelvin and -273.15 celcius. A degree celcius has the same size as a degree Kelvin. The triple point of water is 0.01 celcius. So in Kelvin the triple point of water will be 273.16 (273,15 +0.01) So 1 Kelvin can be defined as the triple point of water divided by 273,16. or 1/273.16 of the triple point of water.
