World Metrology Day: the countdown has begun

PTB-News 2.2018

This year's World Metrology Day (on 20 May) marks the start of the countdown to the introduction of the new International System of Units (SI). The new – or rather revised – SI, in which all units are traced to fundamental constants, will in all likelihood be adopted by the CGPM in November 2018. The revised SI will then officially come into force on next year's World Metrology Day (20 May 2019). This “revolution in the system of units” is a huge challenge for all communicators. PTB's Press & Information Office has therefore given the new SI a warm welcome with a short animation showing the way from “natural feet” to “natural constants”.
