The 2026 Weights and Measures Week theme, “We Measure What Matters,” reminds us that measurement isn’t just for rulers, provers, or scales – it's at the heart of trust in the U.S. marketplace. This year’s holiday coincided with NIST’s 125th anniversary celebration – both wonderful reasons to enjoy cake! The Office of Weights and Measures (OWM) hosted visiting laboratory metrology training participants, their dedicated instructors, and amazing staff who keep OWM’s gears turning. It was a wonderful moment to applaud the U.S. weights and measures community and the impact of NIST.

 Announcing the 2026 OWM "Info Hours" Series
The NIST Office of Weights and Measures is pleased to announce the schedule for the 2026 OWM Info Hours series. An Info Hour is a one-hour session that features current weights and measures, legal metrology, or documentary standard relevant topic while providing a forum for discussion and Q&A. It allows for networking with OWM staff and other subject matter experts (SMEs) in the weights and measures community.
Info Hours are scheduled for the third Thursday of most months in 2026, at 2:00 PM Eastern Time. There is no registration fee or prerequisites required for attendance. All Info Hours will be recorded, uploaded to the e-Learning Resources and Training webpage, and available on demand.
Consensus Value 2026 for the Kilogram
A new 2026 Consensus Value (CV) for the kilogram has been released by the BIPM for the international mass metrology community. This update has important implications for SI traceability, uncertainty budgets, and the calibration of mass standards, particularly for Mass Echelon I calibration laboratories. Register for the free one-hour training on April 28, 2026 to learn what the new CV means in practice and what actions calibration laboratories should consider now.
