say goodbye to the kilogram as scientists vote to replace it
there is a metal kilogram weight deemed so valuable it resides under lock and key in an underground vault in paris. for over a century this relic has been kept safe, protected by three vacuum-sealed bell jars. it’s called the international prototype kilogram, or IPK, a block made of platinum and iridium that defines, not only the weight of a kilogram, but every weight in the world. the world’s scales are also defined according to this weight with copies of it distributed around the world to calibrate every sort of weighing device, from supermarkets to bakeries. and so, since its creation in 1889 its purpose has been to simply exist.
