The kilogram is now a simple truth, an idea that can be carried anywhere in the universe without bothering to bring a cylinder with you.<\/p>\n<p><a href=\"https:\/\/www.livescience.com\/65522-new-kilogram.html\" target=\"_blank\" rel=\"noopener noreferrer\"><\/p>\n<div style=\"clear:both;\">Read more<\/div>\n<p><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The kilogram isn\u2019t a thing anymore.
