Welcome to the National Institute of Standards and Technology (NIST) Office of Weights and Measures (OWM) Contacts System Web Site. The NIST OWM program promotes uniformity in U.S. weights and measures laws, regulations, and standards to achieve equity between buyers and sellers in the marketplace to enhance consumer confidence in the marketplace, enable U.S. businesses to compete fairly at home and abroad, and strengthen the U.S. economy.

The Office of Weights and Measures (OWM) Contacts System is a U.S. Department of Commerce (DOC) system managed by the National Institute of Standards and Technology (NIST) to provide Weights and Measures Officials; Industry Representatives; National Work Group (NWG) Members; and the public with a system for registering for OWM training classes and for requesting, downloading, and/or reviewing a wide variety of weights and measures technical materials and publications. Users may also use the system to update their personal information or to access their personal training history. Users may also use the system to participate in working group activities, including commenting on proposed revisions to laws, regulations, standards, international recommendations, NIST handbooks, and other documents.
