Links between the BIPM and NCSLI

  • NCSLI organizes an annual conference attended by a large number of industries and other professionals that interface with metrology, particularly in (but not limited) to North America. The event is a useful opportunity to disseminate information about developments related to the SI, and in general to raise the profile of metrology and the work of the NMIs.
  • The BIPM is represented in the Board of Directors of NCSLI and attends the annual NCSLI meeting and the Board meeting held adjacent to it.


The vision of NCSLI is to be the world's recognized source for measurement science expertise and information.

Its mission is to provide the best opportunities for the world's measurement science experts and practitioners: to network and exchange information; to promote measurement education and skill development; and to develop means for organizations to resolve measurement challenges.

The BIPM and NCSLI cooperate to increase effective dissemination of information related to the International System of Units (SI) among the NCSLI user community, and to receive feedback from them.
