Description | The paper deals with the changes in the definitions of SI base physical units. The latest changes have affected four of them - kilogram, ampere, kelvin and mole. It is a relatively extensive redefinition that uses universal constants. In addition to introducing the modifications and the history of the kilogram definition, the paper reflects on the impact of these changes on current practice and associated difficulties. |
