World Metrology Day is the annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations. The Convention set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal applications. The original aim of the Metre Convention - the world-wide uniformity of measurement - remains as important today as it was in 1875.
PRESS RELEASE (MUSSD-2026-05-20)
World Metrology Day 2026
Call for Abstracts: Metrology Research Symposium
Theme: “Building Trust in Metrology Policy Making”
World Metrology Day is the annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations. The Convention set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal applications. The original aim of the Metre Convention - the world-wide uniformity of measurement - remains as important today as it was in 1875. The theme of this year's World Metrology Day is building trust through metrology.
To celebrate World Metrology Day this year, the Measurement Units, Standards and Services Department (MUSSD) invites researchers, academics and industry professionals to submit abstracts for the 2026 Metrology Research Conference.
The announcement coincides with World Metrology Day 2026, observed globally on 20 May under the theme “Building Trust in Metrology Policy Making.” The symposium will be officially launched on 20 May 2026, with the main event scheduled for December 2026 in Pitipana Technical City, Homagama.
Who Can Apply
MUSSD welcomes original research and development projects in metrology from:
- MUSSD laboratories and divisions
- Government research and development institutions
- Universities and higher education institutions
- Accredited and non-accredited calibration and testing laboratories
- Other organizations engaged in measurement-related services
Priority areas include trade and commerce, industry, health, environment, road and public safety, food safety, energy efficiency, medical metrology, and other fields where measurement science applies.
Key Dates
Abstract submission deadline: 31 August 2026
Notification of acceptance: 10 October 2026
Symposium: December 2026
Objective
The symposium aims to strengthen Sri Lanka’s National Quality Infrastructure [NQI], support fair trade, consumer protection, and product safety, and promote innovation through reliable measurement science.

PRESS RELEASE
World Metrology Day-20 May 2026 (BIPM-OIML)
Metrology: Building Trust in Policy Making
20 May is World Metrology Day, commemorating the anniversary of the signing of the Metre Convention in Paris, in 1875. This treaty provides the basis for a worldwide coherent measurement system that underpins scientific discovery and innovation, industrial manufacturing and international trade, as well as the improvement of the quality of life and the protection of the global environment.
The theme for World Metrology Day 2026 is "Metrology: Building Trust in Policy Making", which highlights the role metrology plays in providing scientific evidence and legal frameworks that policy makers can use to make informed, transparent and enforceable decisions.
Every day, scientific and legal metrology work hand-in-hand to ensure that the global metrology system supports consumer protection and fair trade, enabling the smooth functioning of markets. From ensuring accurate energy and fuel measurements, to facilitating market transactions, transport safety and environmental monitoring, this agreed framework allows measurements to serve as a trusted basis for decisions that affect citizens, markets and cooperation between countries.
Around the world, National Metrology Institutes (NMIs) are central to this process, continually advancing measurement science by developing and validating new measurement techniques at the necessary level of sophistication. NMIs participate in measurement comparisons coordinated by the Bureau International des Poids et Mesures (BIPM) or by the Regional Metrology Organizations, to ensure the reliability of measurement results worldwide.
Alongside NMIs, national legal metrology authorities play a distinct role in implementing and enforcing legally controlled measurements in line with internationally harmonized requirements.
In support of this work, the International Organization of Legal Metrology (OIML) develops International Recommendations, which aim to align and harmonize requirements worldwide in many fields. The OIML also operates the OIML Certification System (OIML-CS) which facilitates international acceptance and global trade of regulated measuring instruments.
In November 2023, a significant milestone was reached as the UNESCO General Conference, during its 42nd Session, officially recognized the annual celebration on 20 May. This endorsement opens up new avenues to promote metrology, aligning with UNESCO's mission to build a better world through science and education.
