Abstract :
The international community started recently to look for a new way to define the kelvin. Since 2006, different experiments around the world have started to re-determined the Boltzmann constant and more than 7 experiments have obtain an uncertainty below 12 ppm in relative value. This presentation will describe the most promising methods.
