The kilogram is losing weight and many scientists agree that it's time to redefine it. They are hoping to redefine the kilogram by basing it on standards of universal constants rather than on an artifact standard.

"The idea is to replace the single master kilogram with something based on physical constants, rather than an artifact that could be damaged accidentally," says one mechanical engineer.
