Description
The Measure of All Things – a lecture on the redefinition of SI unitsIn November 2018 the General Conference on Weights and Measures has redefined four of the SI units: the kilogram, the ampere, the kelvin and the mole, in terms of the fundamental constants of nature. This means that every unit of measurement will be linked to natural constants, and not physical objects.
World Metrology Day on 20 May 2019 is the proposed date for the redefined SI to come into effect.
Learn about the SI definition from NPL
NPL is celebrating the redefinition of the SI system of units by giving lectures at universities all over the UK about this once-in-a-generation change.
Academic research routinely uses the SI units, but a more thorough understanding of them can support your research.
Also measurement underpins innovation in every industry and a competitive workforce will require expertise in this field.
The one-hour lecture will cover:
- The importance of measurement and how it is at the heart of all science and engineering
- How the accuracy of any measurement is fundamentally limited by how accurately the units of measurement are defined and realised
- The benefits of defining units based on natural constants rather than artefacts
- The significance of the redefinition of the SI base units
