The Kilogram Isn't What It Used to Be—It's Lighter | Materials Science. Sèvres*, France—What I love best about the kilogram is its tangibility, its solid, sculpted form of shiny platinum and iridium.
I’m referring to not just any kilogram but the quintessential one that resides here—the actual International Prototype Kilogram, or IPK, created in 1879 as the official standard of mass. It’s a smooth cylinder of alloy, only an inch and a half high and an inch and a half in diameter. Though petite, the IPK is necessarily dense; it weighs 2.2046 pounds. If you went to pick it up, you might think someone had cemented it to the tabletop for a prank. Even if you knew what to expect, its compact heft would still boggle your senses. Of course, they won’t let you pick it up. They won’t even let you anywhere near it. The IPK is, in and of itself, the International System of Units’ definition of mass.
Although I have come to pay my re-spects to the IPK, I am denied even a glimpse of the thing. . * The dateline incorrectly read, "Sèvres Cedex, France. "
