"Cheese, platinum and fundamental constants – what is the revision of the SI all about?"

Worldwide agreement on units of measurement has brought us freedom to trade and innovate, as well as supported improved wellbeing and trust. This talk will describe why are we changing things now and what the revision of the International System of Units promises for the future. In particular, the redefinition of the kelvin away from the triple of point of water will be described, including the measurements contributing to the final value of Boltzmann's constant and the ongoing implementation of the temperature scale.
