▲De anno [[1889]] 1 kg est, per definitionem, massa quae continetur in exemplari prisco apud [http://www.bipm.fr Officinam Internationale in Pondera et Mensuras] [[Lutetia]]e sito. Exemplar factum est de metallis [[Platinum|Platino]] (90 %) atque [[Iridium|Iridio]] (10 %). In forma cylindri funditum est 39mm alti, cum radio 19.5mm.
