Wired: Kilogram Poses Weighty Problem

Seems like kilogram is finally going to get a makeover. I agree with the proposed decision to switch the definition of kilogram to one based on Avogadro’s Number or the Plank Constant.

From wired.com:

If several scientists get their way, a 2.2-pound hunk of metal — the international prototype of the kilogram — may soon be out of style.
Like its six basic-units-of-measurement siblings before it — including the meter — the kilogram may be moving toward a new definition based on a universal constant.
