Transition de Metrologia vers le libre accès
The Bureau International des Poids et Mesures (BIPM) and IOP Publishing (IOPP) will convert Metrologia, the leading international journal in pure and applied metrology, to a fully open access (OA) publishing model.
The move reflects the growing global demand for open science and underscores both BIPM’s and IOPP’s commitment to making universal access to research a reality. It also aligns with funder mandates that require publicly funded research to be published in OA journals.
From 1 January 2026, all articles published in Metrologia will be freely accessible to readers worldwide, removing barriers to knowledge and significantly enhancing the visibility and impact of the journal’s content.
IOPP, which has co-published Metrologia with the BIPM since 2003, has successfully supported similar transitions to fully OA for the American Astronomical Society, the International Atomic Energy Agency, and the Japan Society of Applied Physics.
“Open access is a natural evolution for Metrologia, ensuring that the journal continues to serve the global metrology community while supporting the principles of transparency, accessibility, and equity in science,” says Dr Martin Milton, Director of the BIPM.
“We’re proud to support BIPM in making Metrologia more accessible to researchers and readers around the world. This transition reflects our shared commitment to open science and to supporting our publishing partners through sustainable and inclusive open access models,” adds Violeta Ribarska, Head of Partner Publishing and Engagement at IOP Publishing.
To support the transition, any articles submitted after 18 August 2025 will be processed as open access submissions. Metrologia will be included in IOPP’s transformative agreements, allowing authors affiliated with participating institutions to publish OA without incurring direct costs.

About the BIPM
The Bureau International des Poids et Mesures (BIPM) is the international organization through which Member States work together on matters related to metrology. The signing of the Metre Convention in 1875 created the BIPM and for the first time formalized international cooperation in metrology.
As the home of the International System of Units (SI) and the international reference time scale (UTC), the BIPM promotes and advances the global comparability and traceability of measurements for scientific discovery and innovation, industrial manufacturing and international trade, improving quality of life and sustaining the global environment.
