Metrologists are measurement artists who are very precise in the case of the Boltzmann constant up to the sixth decimal place. Whoever is able to determine it very exactly will cause a small revolution in the field of worldwide temperature measurement: The temperature unit will then no longer be based – as hitherto – on a chemico-physical material property, i.e. the triple point of water, but on an unchangeable fundamental constant.
