Abstract
A practical realization of a thermometer utilizing Johnson’s noise is presented. At 2019 new definition of SI units was adopted an Kelvin is not based on triple point of water as it used to be before. Boltzmann constant has a fixed value instead from which Kelvin could be derived in various ways.
