Jabarkan Atom-counting approaches dari Kilogram dalam bahasa sunda

The Watt balance uses the current balance that formerly was used to define the ampere to relate the kilogram to a value for Planck's constant, based on the definitions of the volt and the ohm.

The Avogadro approach attempts at defining the kilogram by a fixed count of silicon atoms. As a practical réalization, a sphere will be used where the size is méasured by interferometry.

The ion accumulation approach involves accumulation of gold atoms and méasuring the electrical current required to neutralise them.
