På dette tidspunkt blev længde omdefineret; definitionen blev ændret fra prototypemåleren til et bestemt antal bølgelængder af en spektral linje af en <a href="/wiki/Krypton-86" class="mw-redirect" title="Krypton-86">krypton-86</a>-stråling. </p><p>På dette tidspunkt var SI konstrueret af omkring syv basisenheder, som blev brugt til at konstruere de andre enheder. Redefinitionen i 2019 ændrede SI-systemet til syv definerende <a href="/wiki/Konstant" title="Konstant">konstanter</a>. <br />Et forslag til ændringer: </p> <ul><li>Ud over lysets hastighed, blev fire konstanter - Plancks konstant, Elementarladning, Boltzmanns konstant og Avogadros konstant - omdefineret til at have præcise værdier.</li> <li>Den internationale kilograms-prototype blev fjernet.</li> <li>De nuværende definitioner af kilogram, ampere, kelvin og mol skulle ændres.</li></ul> <p>De nye definitioner blev vedtaget af EU d. 26. november 2018, og trådte i kraft d. 20. maj 2019. </p> <div class="mw-heading mw-heading2"><h2 id="Globalt_brug_af_SI-enheder">Globalt brug af SI-enheder</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SI-systemet&veaction=edit&section=12" title="Redigér afsnit: Globalt brug af SI-enheder" class="mw-editsection-visualeditor"><span>redigér</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=SI-systemet&action=edit&section=12" title="Edit section's source code: Globalt brug af SI-enheder"><span>rediger kildetekst</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dd><span typeof="mw:File"><span><img src="//upload.wikimedia.org/wikipedia/commons/thumb/6/64/Question_book-4.svg/19px-Question_book-4.svg.png" decoding="async" width="19" height="15" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/6/64/Question_book-4.svg/29px-Question_book-4.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/6/64/Question_book-4.svg/38px-Question_book-4.svg.png 2x" data-file-width="262" data-file-height="204" /></span></span> <i>Der er for få eller ingen <a href="/wiki/Wikipedia:Kildeangivelser" title="Wikipedia:Kildeangivelser">kildehenvisninger</a> i dette afsnit, <a href="/wiki/Wikipedia:Verificerbarhed" title="Wikipedia:Verificerbarhed">hvilket er et problem</a>.
