About Metrologia

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).

There is a close relationship and cooperation between the two IOP Publishing journals, Metrologia and Measurement Science and Technology.  Both journals publish articles about metrology. Together they cover the whole measurement chain from realisation of the SI to wider dissemination and application in industrial and academic environments.

Measurement Science and Technology publishes articles on new measurement techniques, associated instrumentation and data analysis that represent an advance in measurement science or measurement technique rather than the application of established experimental techniques. The work published ranges from applied metrology undertaken at National Metrology laboratories to measurement science work undertaken in academic and industrial environments. All submitted articles should contain consideration of the uncertainty, precision and/or accuracy of the measurements presented.

Please note that all submissions to Metrologia require a statement (in under 100 words) detailing the novelty, impact and relevance of your article.

Metrologia also requires that certain guidelines are followed by authors in preparing their articles for submission.

Axes labels in figures; column/row headings in tables:
Labels and headings should be written as ‘Quantity/unit’, for example Wavelength/nm, Temperature/K etc, and not ‘Quantity (unit)’ or in any other format.

No stand-alone unit symbols
Symbols for units should never be used without numerical values or quantity symbols (they are not abbreviations).

Metrologia operates a single-anonymous peer review process, in which the reviewers know the identity of the authors, but the authors do not know the identity of the reviewers.

Our Publishing Support website provides more information on our reviewing process.

Metrologia maintains the highest standards of publication and research ethics. Authors are expected to comply with BIPM’s ethical policy.

Metrologia is moving from a hybrid open access journal to fully open access. All articles published in MET from January 2026 will be immediately free to read anywhere in the world. Original submissions received before August 18^th 2025 will incur our previous OA fees if the article is accepted. Original submissions received after August 18^th 2025 will incur our updated APC (article publication charge).

For original submissions received before August 18^th 2025:

Authors who do not select the Gold open access option can post the accepted version of their manuscript to an institutional or subject repository after a 12 month embargo (with reuse restrictions). The accepted version of an article refers to an author’s original version of an article after any changes made during peer review but before any editing, typesetting, etc. by the publisher.

Gold open access submissions received before August 18^th 2025 will incur the following article publication charge (APC) rates:

For original submissions received on or after August 18^th 2025:

Submissions received after August 18th 2025 will incur the following article publication charge (APC) rates:

*excluding VAT where applicable

There are no other charges for publishing in Metrologia.
