Next week, leading figures in the field are set to make history. At the general conference on weights and measures in Versailles, representatives from 57 nations will vote for change. And so the kilogram, the only metric unit still based on a solitary object, will be reborn. Henceforth, the kilogram will be derived from a fundamental constant, a number that is woven into the fabric of the universe.
In the balance: scientists vote on first change to kilogram in a century
