Redefinition of International System of Units Accepted

-A +A

The resolution for the redefinition of the kilogram, ampere, kelvin and mole was unanimously accepted at the 26th General Conference on Weights and Measures (CGPM) that took place in Versailles, France on 14-16 November 2018.

The Director of TÜBİTAK National Metrology Institute, Mustafa ÇETİNTAŞ, and General Director of Metrology and Standardization, Prof. Dr. Necip CAMUŞCU, attended the CGPM, the highest-level decision making body established by the Metre Convention, is held every 4 years.

This resolution, accepted through the votes of 60 different representatives from countries that have signed Metre Convention, means international units (SI) are now to be defined in terms of constants drawn from the natural world. This decision will provide for the future stability of the SI and allow the use of new technologies, including quantum technologies, to realize definitions in the laboratory. The changes, which will come into force on 20th May 2019, will bring an end to the use of physical artifacts to define measurement units.

On the other hand, for the first time since its establishment in 1992, a Director of TÜBİTAK UME was invited to speak at the General Conference on Weights and Measures. Mustafa ÇETİNTAŞ made a presentation on TUBITAK UME’s contribution to the Capacity Building and Knowledge Transfer Programme run by the BIPM through the BIPM – TUBITAK UME Project Placements, a long term training programme aimed at developing metrology institutes.

This invitation to TÜBİTAK UME, which has gained a higher profile in the world of metrology with the quality of its services to over 40 countries all over the world in recent years, is a recognition of TUBITAK UME’s scientific achievements and contributions to the world of metrology by the BIPM.
