The Kilogram seems to be on a diet!

How else do you explain this from Good Morning Silicon Valley?

You may not have known it, but there is one "official kilogram," a cylinder cast in 1889 from a platinum and iridium alloy, measuring 1.54 inches in diameter and height. There are dozens of copies, but the reference kilo is kept in a triple-locked safe at a French chateau and is only brought out for periodic comparison with its brethren. And now, that comparison has produced a mystery. In comparison to an average of the copies, the reference kilo has lost weight -- about 50 micrograms, the equivalent of a fingerprint.

"The mystery is that they were all made of the same material, and many were made at the same time and kept under the same conditions, and yet the masses among them are slowly drifting apart," said physicist Richard Davis of the International Bureau of Weights and Measures. "We don't really have a good hypothesis for it." Whatever the cause, the apparent fluctuation may push along a move to base our measurement standards on something more precise than a 19th century chunk of metal.

I am sure a handful of people would have lost a lot of sleep and weight over this!

But let us be glad that our local milk-men, vegetable vendors and the lot haven't realised this yet!
