Didn’t they say that the standard kilogram was losing weight a couple of years ago . . . ?

Kilogram Is Losing Weight: Redefine Kilogram Based On Universal Constants, Scientists Urge

[ErnBatavia]

About thirty years ago, when I was in the seafood biz, the standard pack for shrimp was five pound blocks....

Then along came imports from Asia and the western Pacific, packed in 2 kilo blocks (4.4 pounds).....more than one dealer would repack/remark those and pick up the difference as pure profit.

All these blocks were cased in block ice, so the takeaway wasn't so obvious.

Definite "weight gain"!

If the Standard kilogram has gained weight (mass), then I have lost a corresponding amount. Hooray!

[Lonesome in Massachussets]

Weight and mass are two different things. The kilogram is a unit of mass, and is the only fundamental physical quantity still defined by an artifact.

[I want the USA back]

Another misleading headline. The Kilogram has not gained weight. The Kilogram is a weight, not an object.

Also, if this object is the standard by which all other weight measurements are verified, then I have to ask, how can anyone verify the weight of this object?

But ozone and ultraviolet light could be used to clean the kilograms without damaging them, the research suggests.

Oh heck, just run over to Autozone and get some automotive rubbing compound and that should take care of it real quick, no big deal, it'll just buff right out :)

Odd that a science magazine would get the terminology so wrong.

A kilogram is a unit of MASS
Weight is a form of FORCE

The standard kilogram would have zero weight in space, but would still be one kilogram even without gravity.
