Realisation (metrology)

In metrology, the realisation of a unit of measure is the conversion of its definition into reality. The International vocabulary of metrology identifies three distinct methods of realisation:

  1. Realisation of a measurement unit from its definition.
  2. Reproduction of measurement standards.
  3. Adopting a particular artefact as a standard.

The International Bureau of Weights and Measures maintains the techniques for realisation of the base units in the International System of Units (SI).
