Abstract

On November 16, 2018, the 26th General Confer-ence on Weights and Measures voted unanimously to revise theInternational System of Units from a system built on seven baseunits to one built on seven defining constants and will officiallybecome effective on May 20, 2019, or World Metrology Day. Morespecifically, the unit of mass, the kilogram, will be realized via afixed value of the Planck constant hand a Kibble balance (KB) serves as one method of achieving this. Over the past few decades, national metrology institutes around the world have developed KBs, the majority aimed at realizing the unit of mass at the 1-kg level with uncertainties on the order of a few parts in 108. However, upon fixing the Planck constant, mass can be directly realized at any level, deeming the kilogram only a historically unique benchmark. At the National Institute of Standards and Technology, a tabletop-sized Kibble balance (KIBB-g1) designed to operate at the gram-level range with uncertainties on the order of a few parts in 106 is currently under development
