SI Kilogram is about to change

Postby zetreque on March 9th, 2018, 12:14 am
The kilogram remains the only SI unit represented by an unstable artifact. So in 2014, members of the General Conference on Weights and Measures, the international body which oversees the SI system, voted to redefine the kilogram in terms of Planck's constant, a fundamental constant of quantum mechanics.

If approved, the updated and fixed values will come into effect from May 20, 2019, on World Metrology Day.

The temperature SI kelvin, units mole, and electricity ampere will probably change too.
