The kilogram is about to be redefined

Reality is about to change. The kilogram which until now, has been defined as the mass of a certain artefact (or big K) held in a vault in Paris. They will define the kilogram by defining as planks constant as exactly 6.62607015 X 10^-34 Js. This then determines how big a kilogram is.

This will mean that the values for the kelvin, mole and ampere will all now be fixed.

Avogadro's constant will be 6.02214076 X 10^23
The charge on an electron will be 1.602176634X10^-19C
Boltzmann constant = 1.380649X10^-23J/K

This thread is a duplicate of this one http://www.internationalskeptics.com...ad.php?t=90329. Started in 2007. So the discussion has been going on for some time. Come to think of it my science teacher mentioned it in the 1970s.
