Vse enote mase se trenutno izpeljujejo iz tega t. i. mednarodnega prototipa kilograma &#8211; od mikrograma zdravil, kilograma jabolk, do tone cementa. Te\u017eava pa je v tem, da ta prototip nima ves \u010das enake te\u017ee. \u010ceprav je pod tremi steklenimi zvonovi, se na njem nabereta prah in umazanija, nanj pa vpliva tudi atmosfera. V\u010dasih ga morajo celo oprati.<\/p>\n<p>Danes potrjena definicija temelji na vrednosti Planckove konstante, na podlagi katere je s Kibblovim mehanizmom mogo\u010de izmeriti natan\u010dno maso predmeta, pri \u010demer se uporabi natan\u010dno izmerjena elektromagnetna sila.<\/p>\n<p>Danes so spremenili tudi definicije treh drugih enot iz mednarodnega sistema enot, in sicer ampera, kelvina in mola. \u0160tiri nove definicije se bodo pridru\u017eile sekundi, metru in kandeli, ki so jih \u017ee na novo definirali. Tako bo vseh sedem enot iz mednarodnega sistema opredeljenih z naravnimi konstantami, in ne s fizi\u010dnimi predmeti. Vrednosti se z novimi definicijami, ki bodo za\u010dele veljati 20. maja 2019, ne bodo spremenile.<\/p>\n<p>Medtem ko je definiranje sekunde leta 1967 prispevalo k la\u017ejemu komuniciranju v svetu prek sistema GPS, bodo nove \u0161tiri definicije vplivale na podro\u010dja znanosti, trgovine, zdravja in okolja, so zapisali na spletni strani mednarodnega urada.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr\u017eave \u010dlanice Mednarodnega urada za ute\u017ei in mere, med njimi tudi Slovenija, so danes v francoskem Versaillesu soglasno potrdile novo definicijo kilograma in \u0161e treh drugih osnovnih merskih enot.
