Our work enables the next generation of equitable standards to promote US economic growth and security.</p> <p><strong>Our Mission</strong> is to foster the next generation of SI-traceable dimensional, thermodynamic, and optical radiation measurements and their application by providing calibrations, standards, and innovations that improve U.S. industrial competitiveness and quality-of-life.</p> <p>SSD has institutional responsibility for the realization and dissemination of 3 of the 7 base units of the International System of Units (SI): the meter, the kelvin, and the candela. To promote world-wide standardization, SSD staff engage with the Consultative Committees for Length (<a href="https://web.archive.org/web/20230314214431/https://www.bipm.org/en/committees/cc/ccl/">CCL</a>), for Mass and Related Quantities (<a href="https://web.archive.org/web/20230314214431/https://www.bipm.org/en/committees/cc/ccm/">CCM</a>), for Photometry and Radiometry (<a href="https://web.archive.org/web/20230314214431/https://www.bipm.org/en/committees/cc/ccpr/">CCPR</a>), and for Thermometry (<a href="https://web.archive.org/web/20230314214431/https://www.bipm.org/en/committees/cc/cct/">CCT</a>) under the International Committee for Weights and Measures (<a href="https://web.archive.org/web/20230314214431/https://www.bipm.org/en/committees/cipm/">CIPM</a>). This participation helps ensure the international comparability and international recognition of the SI-based measurements and standards disseminated by the Division. As pictured below, the division is divided into 3 technical areas which align with these 3 base SI units.</p> <figure class="align-center nist-image"><img alt="sensor science division flowchart" height="408" loading="lazy" src="/web/20230314214431im_/https://www.nist.gov/sites/default/files/styles/960_x_960_limit/public/images/2021/04/12/sensor-science-division-layout.PNG?itok=RJ1IHEg8" typeof="foaf:Image" width="759"><figcaption class="nist-image__caption"><div class="nist-image__caption-content" data-caption-editable="true"> </div> </figcaption></figure><p>The division provides measurement science, reference materials, reference data, and technologies to foster innovation and confidence in measurements needed to advance these fields. In partnership with U.S. industry, government agencies, and scientific institutions, SSD performs fundamental and applied research on the measurement of length; temperature; infrared-to-extreme-ultraviolet radiation; pressure and vacuum; surface and interface optical and dimensional properties; gas and liquid flow; liquid volume; and humidity.</p> <h2
