It even had a nickname: Le Grand K (The Big K). The accuracy of every measurement of mass or weight worldwide, whether in pounds and ounces or milligrams and metric tons, depended on how closely the reference masses used in those measurements could be linked to the mass of the IPK.</p> <p>That situation has changed radically. In November 2018, the international scientific community voted to redefine the kilogram, freeing it from its embodiment in one golf-ball-sized artifact, and basing it instead on a constant of nature. That transformation was as profound as any in the history of measurement. <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="60849a26-85a2-4241-8ad8-a24940c66f02" href="/web/20230314214441/https://www.nist.gov/si-redefinition/kilogram-introduction" title="Kilogram: Introduction"><strong>MORE</strong></a></p> </div> </div></div> </div> <div class="paragraph paragraph--type--dynamic-content-list-ou paragraph--view-mode--default"> <div class="nist-block "> <h2 class="nist-block__title"> <div class="string">News and Updates</div> </h2> <div class="viewsreference"><div class="views-element-container"><div class="js-view-dom-id-053e52307455cb710f4e577791312542a0a0d136bfa8d3d3ad6fbed01a5510ad"> <div> <article role="article" about="/news-events/news/2023/01/artifacts-begone-nist-improves-its-flagship-device-measuring-mass" typeof="schema:Article" class="nist-teaser"> <div class="nist-teaser__image"> <div class="entity-reference"> <a href="/web/20230314214441/https://www.nist.gov/news-events/news/2023/01/artifacts-begone-nist-improves-its-flagship-device-measuring-mass" hreflang="en"><img src="/web/20230314214441im_/https://www.nist.gov/sites/default/files/styles/thumbnail/public/images/2023/01/18/NIST4-wheel.png?itok=zLUYyUHY" width="67" height="100" alt="NIST-4 Kibble balance" loading="lazy" typeof="foaf:Image"/> </a> </div> </div> <div class="nist-teaser__content-wrapper"> <header> <h3 class="nist-teaser__title"><a href="/web/20230314214441/https://www.nist.gov/news-events/news/2023/01/artifacts-begone-nist-improves-its-flagship-device-measuring-mass"><span property="schema:name">Artifacts, Begone!
