The New SI: The International System of Units is getting a Makeover

Ian Mills / Roberto Marquardt
Published Online: 2019-01-07 | DOI: https://doi.org/10.1515/ci-2019-0108


Metrology, the science of measurement, is part of the essential but largely hidden infrastructure of the modern world. We need it for high-technology manufacturing, human health and safety, the protection of the environment, global climate studies, information transfer and the basic science that underpins all these. Highly accurate measurements are no longer the preserve of only the physical sciences and engineering. The International System of Units, the SI (Système International d’unités), provides the internationally agreed means by which we make such measurements.
