Abstract
The 2019 redefinition of the kilogram in the International System of Units (SI) connects the unit of mass with Planck's constant (h) through electrical metrology by means of precision balances. This not only changes the way the mass is defined, but also broadens the horizon for a direct realization of other physical units. Since mass measurement is essentially a force measurement scaled by the local gravitational acceleration, any physical action providing a force can be measured using a precision balance as a primary standard, connecting it to Planck's constant.Proceedings Title
