Interesting article. It's always amused me that our official "things" are oftentimes actual units. Some have been changed over the years to be things that you can measure, but many - like the kilogram - are actual weights sitting there somewhere.
And yet, it's gained weight. Or lost it.
No matter though - a kilogram is also a liter of pure water at sea level. So we can always go back to that, relegating the lump in Paris to a museum artifact.
