Abstract
Different options were discussed before reaching the final agreement on the new definitions of the SI units, especially with regard to the kilogram. A definition of the kg based on a mass, such as an atom or the electron, would have been preferable for ease of understanding, among other reasons. In this paper we will discuss some educational experiences on ways to teach what is now a kilogram to dif-ferent audiences, including people that is rather unaware of the Planck constant.
