The 26th General Conference of CGPM held in Versailles from 13-16 November 2018 attracted global media attention because of the approval of a resolution to revise the international system of units (SI) so that they are all now linked to physical constants. Agreement was reached to redefine four of the seven base units of the SI – the kilogram, the ampere, the kelvin and the mole.
The new definition of the kilogram attracted most attention because it means that the famous International prototype of the kilogram, (sanctioned by the first CGPM in 1889 and kept at the Pavillon de Breteuil near Paris), is now linked to the Planck constant.
Amid this excitement there was a conference which included presentations of the practical application of metrology to every day life. On behalf of JCTLM Graham Beastall gave a presentation entitled “Traceability in laboratory medicine: a driver of accurate results for patients.” This presentation is available for download here
