Metrology: CAS Zone 3 · Engineering (2026 Xinrui edition); impact factor 2.1 (journal website); fully open access; APC charged, amount not published; review about 6 weeks (community reports); 80 articles in 2025; indexed in ESCI and Scopus.
Scope
Aims, scope and focus
Metrology is published by MDPI AG and is classed under Engineering in the CAS Journal Ranking. By OpenAlex counts of its recent articles, its largest topics are Advanced Measurement and Metrology Techniques, Scientific Measurement and Uncertainty Evaluation and Optical measurement and interference techniques, together about 37.7% of its articles. (generated from OpenAlex topic counts and CAS ranking data)
The name Metrology hints that the journal’s focus is on the formal definition of metrology—“metrology is the science of measurement and its application” [1]—where it is noted that metrology includes all theoretical and practical aspects of measurement, regardless of what the measurement uncertainty and field of application may be. This broad scope does not imply that any modeled or physical measurement can be published in Metrology; rather, the journal is concerned with innovative concepts, new perspectives, and illustrations of applications from which other readers can benefit, operating beyond the traditional boundaries between metrology fields. Basic metrological concepts such as uncertainty evaluation and traceability to the seven base units of the International System of Units and the derived units are the natural background and requirement for all contributions. Metrology covers a broad range of areas, such as studies related to the following topics: Traceability to SI units of complex measurement systems; Measurement theory in a broad context; Measurement uncertainty and uncertainty evaluation; Considerations on the fundamentals of measurement; Error separation methods; Novel methods inspired by the redefinition of the SI; Artificial intelligence, especially its effect on traceability; Machine learning for metrology; Precision measurement; Digital twins; Metrology for sustainable manufacturing; Precision manufacturing; Measurement techniques and devices; Interferometry; XCT measurements; Three-dimensional metrology; Frequency metrology; Surface metrology; Biomedical measurement; Virtual measurement; Power measurement. Sensor calibration. International vocabulary of metrology – Basic and general concepts and associated terms, 2012, Joint Committee for Guides in Metrology (JCGM).
