Metrologia

Aims & Scope

Metrologia covers the fundamentals of measurements, particularly those dealing with the seven base units of the International System of Units (metre, kilogram, second, ampere, kelvin, candela, mole) or proposals to replace them.

The journal also publishes papers that contribute to the solution of difficult measurement problems and improve the accuracy of derived units and constants that are of fundamental importance to physics.

In addition to regular papers, the journal publishes review articles, issues devoted to single topics of timely interest and occasional conference proceedings.

Letters to the Editor and Short Communications (generally three pages or less) are also considered.

In support of the CIPM Mutual Recognition Arrangement (MRA), the web-based Technical Supplement to Metrologia publishes final reports of key and supplementary comparisons.

Launched in 1965 and published by IOP Publishing on behalf of the Bureau International des Poids et Mesures (BIPM) since 2003, Metrologia is an international journal dealing with pure and applied metrology.
