About This Show
AI-drafted summaryThe National Conference on Weights and Measures (NCWM) Annual Meeting is the flagship gathering of the organization now formally known as the National Council on Weights and Measures. The 2026 edition marks the 111th Annual Meeting, bringing together state and local weights and measures officials, federal agencies, device manufacturers, retailers, and other stakeholders. NCWM is a professional not-for-profit association that has developed national weights and measures standards since 1905.
The meeting is where the industry advances the uniform standards that NIST publishes in Handbook 44 (Specifications, Tolerances and Other Technical Requirements of Commercial Weighing and Measuring Devices), Handbook 130 (Uniform Laws and Regulations), and Handbook 133 (Checking the Net Contents of Packaged Goods). Attendees participate in committee work, technical sessions, and the standards-development process that keeps national regulations current with new technology.
Professionals attend to shape and stay current on the model standards that govern commercial measurement across the United States, to network with regulators and industry peers, and to engage with the National Type Evaluation Program (NTEP). Because voting on standards is limited to state and local regulatory officials, the meeting offers a rare, balanced forum where regulators and regulated industries collaborate on fair, equitable standards.

History
NCWM traces its origins to 1905, when the National Bureau of Standards called for a meeting of the states to address the lack of uniform standards and, in many cases, regulatory oversight. Participants decided to meet again the following year, marking the birth of the National Conference on Weights and Measures. The organization's first model standards were published in 1915 as tolerances and specifications for weighing and measuring devices.
Over a century later, NCWM has evolved into a not-for-profit corporation with full-time staff and volunteer leadership. It established the National Type Evaluation Program (NTEP) in 1984. In 2024, the organization changed its name to the National Council on Weights and Measures to clarify that it is more than just a meeting. The 2026 gathering in Philadelphia is the 111th Annual Meeting.
