50µg is very little and i'd like to know what kind of reference they are using. gravity for one isn't really constant and i don't know of any direct mass measurement.

Mechanics in Britain is awfully hard to understand and also when somthing is built useing the Metperial method sized nuts and bolts you need a completely new set of tools, they just wanted to be different??
On topic about the bars weight loss could be due to a few bumps on the way to the scales knocking a few micoscopic particles off it "Over the years". Or possible somthing in the atmosphere is dissolving it? Could there be somthing altering the local gravity?edit on 26-1-2011 by dniMnepO because: (no reason given)

Gravity varies from place to place, especially over volcanic zones. I kind of wonder if something is changing under paris.

My preferred method of measurement is based on the length of a kings foot. Just saying
anyways, the kilogram has not changed, the mass they used to determine what a kilogram is has changed, a kilogram is still a kilogram. Worst case scenario, get a new 1 kilogram mass of platinum-iridium.
Wuts the big deal?

...I think the American Bureau of Standards has their own weights.

Why can't we find a universal, gravitational constant?

The likely cause is radiation from space, Gamma ray. neutrinos, and cosmic rays passing through the metal are knocking atoms apart causing the loss of weight.
