Au Revoir, Original Kilogram


Saturday, May 25, 2019, 11am

A new international unit system that bases the kilogram on seven physical constants will come into effect on May 20, 2019. Up until now, the kilogram has been defined by the mass of a metal cylinder that is locked in a vault near Paris.  With the new system however, the kilogram will be defined by Planck’s constant.

The new unit system will be explained in-depth in this talk. Various experiments will show different examples of how the unit of mass will be defined in future.
