Metrologia is an international journal dealing with the science of measurement and its applications. It publishes experimental and theoretical works representing new and significant advances in metrology. Fields of interest include physics, chemistry, engineering, and biological sciences.

Regular papers deal with the foundations of measurement; measurements improving our knowledge of the fundamental constants; realisations of the units of the International System of Units (SI); the solution of difficult measurement problems; groundbreaking measurement techniques, data analysis and the expression of uncertainty.

Additionally, the journal publishes Reviews, Letters to the Editor, and Short Communications. A special category called ‘Guides, Standards and Conventions’ is devoted to documents adopted by the advisory committees of the International Committee of Weights and Measures (CIPM).

Special issues highlighting topics of timely interest are collated with the assistance of Guest Editors.

Metrologia also has a web-based Technical Supplement that publishes the final reports of key and supplementary comparisons in support of the CIPM Mutual Recognition Arrangement (CIPM MRA).
