The great revolution in metrology began with the redefinition of the Metre in terms of the wavelength of light. From antiquity, practical dimensional measurement standards had all been based upon material artifacts and measurement of time on the rotation of the Earth.

All of that changed in 2018 when the base units of the SI were redefined in terms of fixed values of a set of fundamental and atomic constants.

The lecture will explain how practical measurement standards can be obtained from such definitions.
