Realisation_(metrology)
Realisation (metrology)
Conversion of the definition of a unit of measure into reality
In metrology, the realisation of a unit of measure is the conversion of its definition into reality.[1] The International vocabulary of metrology identifies three distinct methods of realisation:
- Realisation of a measurement unit from its definition.
- Reproduction of measurement standards.
- 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).[2]
