The Weight of Progress: How the CCM is Advancing Measurement Science for a Changing World

The Consultative Committee for Mass and Related Quantities (CCM) Strategy outlines the global roadmap for advancing measurement science in mass and related quantities over the next decade. Building on the 2019 redefinition of the kilogram, the strategy emphasizes three core aims: progressing measurement science, promoting global comparability, and improving stakeholder engagement. Further, it addresses seven “grand challenges” identified by the CIPM—spanning climate change, health, food safety, energy, advanced manufacturing, digital transformation, and emerging metrology—where enhanced traceability and precision in mass-related measurements can yield societal and industrial benefits.

The CCM’s plan includes advancing experimental methods such as Kibble and micro-Kibble balances, optical cavity pressure sensors, and cold-atom gravimeters; managing the transition to sovereign kilogram realizations; and fostering digital transformation through initiatives like digital calibration certificates and data-driven comparability. Collaboration remains central, with strong ties to RMOs, ISO, ILAC, OIML, and other Consultative Committees. The BIPM laboratories play a pivotal role by coordinating key comparisons, maintaining reference standards, and supporting knowledge transfer.

This talk will summarize the CCM’s vision of a world where all measurements of mass and related quantities are globally comparable and traceable to the SI, highlighting key milestones, research priorities, and international coordination efforts guiding metrology into a more connected, digital, and sustainable future.

OIML: Enabling Innovation for a Sustainable Future

The International Organization of Legal Metrology (OIML) plays a pivotal role in fostering innovation while ensuring global measurement standards that support sustainable development. As industries transition toward greener technologies and digital ecosystems, accurate and reliable measurements become essential for energy efficiency, resource optimization, and environmental protection. This presentation explores how OIML enables innovation through harmonized standards, digital transformation, and collaborative frameworks that address emerging technologies such as smart sensors, renewable energy systems, and data-driven metrology. By aligning legal metrology with sustainability goals, OIML not only strengthens trust in measurements but also accelerates progress toward a resilient, inclusive, and environmentally responsible future.

“The Gravitational Constant G Shapes the Cosmos - The History of Measuring a Fundamental Physical Constant.”

The gravitational constant, G=6.67430(15)×10^-11 N m^2/kg^2, is one of the fundamental physical constants that shape the cosmos as we know it today. Had G taken a different value, the nature of astrophysical objects would have been entirely altered, and life itself might never have emerged. Why does G possess this particular value--so much weaker than other fundamental forces, such as electromagnetism, by many orders of magnitude? Modern physics offers no definitive answer to this profound question. In this talk, I will review the history of humanity’s quest to determine G, tracing back to the eighteenth century.

“Future Directions of Manufacturing Shaped by the Circular Economy”

In recent years, the Circular Economy (CE) has been attracting increasing attention. It is founded on two pillars: production based on recycled resources and value creation that is not dependent on material throughput. CE should be regarded as a powerful catalyst for transitioning toward a new paradigm of manufacturing, moving away from the unsustainable mass production and mass consumption. This lecture introduces an overview of CE with some enabling ideas including corporate ecosystems led by circulation providers, product life cycle design, business models, and digitalization.

“Extreme Measurements and Gravitational Wave Astronomy”

A century has passed since Einstein predicted gravitational waves, and we are now in an era where gravitational waves are regularly observed, and the data can be used to explore the mysteries of the Universe. To observe gravitational waves, it is necessary to measure extremely small expansions and contractions of space, and it is largely due to the development of technology over the past decades that such observations have become possible. In this lecture, I would like to introduce the measurement technology that makes gravitational wave observations possible, introduce the KAGRA project that we are currently working on, and talk about the mysteries of the Universe that gravitational wave astronomy will unravel.

“Current Status and Challenges of Certified Measurers’ Activities in Kyushu”

Kyushu, located in southwestern Japan, consists of seven prefectures plus Okinawa.
As one of the certified measurers working in Kyushu, This presentation outlines the current status of substitute inspections—commonly referred to as dai-kensa—conducted by certified measurers in place of periodic governmental inspections, which are performed for a wide range of businesses—from large companies to small individual shops.
Drawing on practical experience as an active certified measurer in Kyushu, the presentation highlights key operational challenges, emerging issues, and regional characteristics associated with these activities.
*Certified measurers are nationally certified professionals registered by the Minister of Economy, Trade and Industry under the Measurement Act in Japan, and are responsible for managing and ensuring accurate measurements at companies and business establishments.

“Digital Transformation Attempts in OIML CS 
---- Remote Test of OIML R76”

The OIML Test Laboratory of the National Institute of Metrology, China (NIM), in close collaboration with weighing instrument manufacturer METTLER TOLEDO, has proactively explored an innovative testing approach and developed the forward-looking OIML R76 Remote Testing System, which is based on the integration of robotic and network information technologies. This system comprises an OIML R76 automated testing device installed at the manufacturer's testing site, which is equivalent to personnel from NIM conducting the OIML test on-site; therefore, it can also be called a Remote Test Laboratory (RTL). Furthermore, through the calibration traceability of test weights and real-time encrypted and reliable data transmission, the system meets the requirements of ISO/IEC 17025.
The RTL can be regarded as a balanced solution that leverages digital technology to ensure impartiality, enhance the efficiency of OIML certification, and shorten the product launch cycle. NIM and MT are currently jointly developing and researching this new type of RTL to promote the digital transformation of OIML-CS work.
