Abstract
The redefinition of the SI unit the kelvin in May 2019 has opened new possibilities for the realization, dissemination and measurement of temperature. Besides the two practical scales that were in place before the redefinition, now, through the mechanism of the mise en pratique for the definition of the kelvin, temperature can be realized and disseminated through primary thermometry approaches with direct traceability to the redefined kelvin. In the medium to long term practical primary thermometry approaches could be developed allowing for in-process driftless thermometry.
