NIST OWM’s principal mandate to “fix the standard of weights and measures” is explicitly stated in the U.S. Constitution. Also, the “Office of Standard Weights and Measures” was formed in 1836 as part of the Coast and Geodetic Survey and predated the formation of the National Bureau of Standards (NBS) which was renamed the National Institute of Standards and Technology (NIST) in 1988. This makes the Office of Weights and Measures (OWM) the oldest office at NIST. Learn more About OWM here.
What is also not well known is that a critical need for accurate weights and measures (and other standards) in the late 1800s prompted the U.S. Congress (in 1901) to transform the Office of Weights and Measures into NBS as the U.S. National Metrology Institute (NMI). Learn more about the History of OWM and NIST’s History of Standards here.
At OWM, we are mindful of the Office's significant history and the roles and responsibilities that come with it. We are also very proud of the present-day importance of our weights and measures function in providing foundational metrology training services for NIST as the U.S. National Metrology Institute (NMI) and underpinning a large portion of the U.S. economy.
NIST’s chief metrologist, James Olthoff, recently explained how NIST, as the U.S. NMI, is part of a harmonized international measurement system that contributes to trust in consumer products and goods, new technologies, and global trade.
