The IPK has been the global standard for mass for the last 125 years; it was sanctioned at the first General Conference on Weights and Measures (CGPM) on 7-9 September 1889 in Paris. This is likely to be the last landmark birthday of the IPK as current experiments to redefine the kilogram are due for completion as early as 2018. These will relate mass to naturally occurring constants rather than a physical object such as the IPK.
