It's official! The kilogram is no longer defined by a piece of metal in Paris. The kg and other SI units are now rooted in precise quantum constants, pushing our precision to new heights . via #WorldMetrologyDay
This is the real throne that has fallen!. The old ways are done! Good riddance, imperfect metal ingot! All hail our new celestial mass --- the kilogram standard, as fixed by the laws governing the very tiniest constituents of matter. Hurrah!!!!
Good morning. Meet your new kilogram standard.
The new kilogram just debuted. It’s a massive achievement.The new definition represents a victory of humankind over chaos in the universe. Really.
The passing of the physical kilogram makes me kind of sad.
