PTB's international tasks include participating in various metrological organizations and cooperating with National Metrology Institutes all over the world, as well as technical cooperation with developing countries and countries in transition. In all instances, there is primarily one goal: the international harmonization of metrology. If all people are to trade with each another without difficulty, then a kilogram has to really be a kilogram all over the world, a meter has to be exactly a meter, and so on. A great number of measures and rules have to be in agreement. This goal has been largely reached in Europe, but at the global level, it still has some way to go. Various international agreements are milestones on the way towards international uniformity. In the list below you can find some of the organizations which are important worldwide. European metrology organizations are to be found under
Metrology in Europe.
