In 2018, physicists change the way of defining fundamental units like kilograms or meters. Units can now be defined based on scientific methods using only fundamental constants and well-established theories. No more prototypes, stallions or human references. Here are the 7 new « user manuals » to make these units, downloadable under various formats freely.
