Issue 4: Metrology for the Digitalization of the Economy and Society
[ more ]
After nearly 130 years of service, the international prototype of the kilogram is expected to be retired in the fall of 2018 (at the General Conference on Weights and Measures). The Avogadro experiment, which aims to determine the number of atoms contained in a near-perfect silicon sphere, is a cornerstone of the redefinition of the kilogram.

PTB - The National Metrology Institute of Germany

PTB's profile of tasks

In Braunschweig and Berlin, time comes from atomic clocks, lengths are measured far into the nano-world, scientists do research on fundamental questions concerning the physical units, and the employees in the laboratories calibrate measuring instruments, meeting the most demanding requirements. Therefore, the Physikalisch-Technische Bundesanstalt is among the top names in metrology worldwide. As Germany's national metrology institute, PTB is Germany's highest authority when it comes to correct and reliable measurements. It is the supreme technical authority of the Federal Ministry for Economic Affairs and Energy (BMWi) and employs a total of approx. 1900 staff members. PTB operates an integrated Opens internal link in current windowquality management system which covers the four interlinked field of business.
