Abstract

The redefinition of the kilogram in 2019 in terms of a fixed numerical value of a constant of nature, the Planck constant h, created the opportunity for the realisation of mass at any point on the scale and improvement in the uncertainty at sub‑gram scales. In this work, part of the route to measurement of mass at small scales at the National Physical Laboratory (NPL) will be described. The aim is to miniaturise a system based on the planned NPL Next Generation Kibble Balance to a simplified gram level Kibble Balance. This is a preparatory step for future work on a micro-electromechanical system (MEMs) scale Kibble Balance.
