3/2/2023 - Weights and Measures Week


Happy Weights and Measures week!


Weights and Measures Week is celebrated every year from March 1 to 7 to commemorate President John Adams signing the first U.S. weights and measures legislation into law on March 2, 1799. NIST SP 447, Weights and Measures Standards of the United States, A Brief History (PDF) provides insight into the fascinating history of measurement system development. Looking for education resources to support Weights and Measures Week activities in the classroom or outreach event? Explore the NIST Educational STEM Resource Registry (NEST-R).

As John Quincy Adams so aptly put…”Weights and Measures may be ranked among the necessaries of life to every individual of human society.” Join the U.S. Weights and Measures community in celebrating national Weights and Measures Week using the social media hashtag #ThankAnInspector!
