Global standard for kilogram

Global standard for kilogram

Photo taken on Nov. 2, 2018, at Japan's National Institute of Advanced Industrial Science and Technology in Ibaraki Prefecture shows a copy of the metal cylinder that has served as the global standard for the kilogram. The media were given a rare chance to see the copy, heavily guarded in a double-glass case and being held in a safe with five layers of security doors. It was made from the international prototype of the kilogram that was made about 130 years ago and has been held in France under tight security. (Kyodo) ==Kyodo
