He proposed a universal toise (French: Toise universelle) which was twice the length of the seconds pendulum.

However, it was soon discovered that the length of a seconds pendulum varies from place to place: French astronomer Jean Richer had measured the 0.3% difference in length between Cayenne (in French Guiana) and Paris. The organisation is commonly referred to by its French initialism, BIPM.

Conformity Assessment is the demonstration that specified requirements relating to a product, process, system, person or body are fulfilled. Biro Internasional untuk Ukuran dan Timbangan (BIPM; bahasa Prancis: Bureau international des poids et mesures; bahasa Inggris: International Bureau of Weights and Measures), adalah sebuah organisasi antarpemerintah di mana setiap negara anggota secara bersama-sama melakukan penelitian dan pengawasan hal-hal yang berhubungan dengan ilmu-ilmu dan standar-standar pengukuran. For a long time, the meter was precisely defined as the length of an actual object, a bar kept at the International Bureau of Weights and Measures in Paris. The International Prototype of the Kilogram, the sole remaining physical prototype of an SI unit, is kept at the Bureau, as well the International Prototype of the Meter. Currently, main work of the BIPM include:[6], The BIPM has an important role in maintaining accurate worldwide time of day. A note on some other examples of international organizations established with the name "Bureau" at that time is available: The Convention, modified slightly in 1921, remains the basis of international agreement on units of measurement. [5] The status was further clarified by the French decree No 70-820 of 9 September 1970.[4]. The BIPM is supervised by the International Committee for Weights and Measures (French: Comité international des poids et mesures, CIPM), a committee of eighteen members that meet normally biannually[clarification needed], which is in turn overseen by the General Conference on Weights and Measures (French: Conférence générale des poids et mesures, CGPM) that meets in Paris usually once every four years, consisting of delegates of the governments of the Member States and observers from the Associates of the CGPM. The following year the French government made available to the organization an estate at Sèvres, near Paris, where it is still located. This task takes many forms, from direct dissemination of units to coordination through international comparisons of national measurement standards (as in electricity and ionising radiation). Our vision is to be universally recognized as the world focus for the international system of measurement. Since 1985 the Bureau has also been responsible for maintaining Atomic Time. scientific and technical activities carried out in its four departments: chemistry, ionising radiation, physical metrology, and time; liaison and coordination work, including providing the secretariat for the CIPM Consultative Committees and some of their Working Groups and for the CIPM MRA, and providing institutional liaison with the other bodies supporting the international quality infrastructure and other international bodies; capacity building and knowledge transfer programs that aim to increase the effectiveness within the worldwide metrology community of those Member State and Associates with emerging metrology systems; a resource centre providing database and publications for international metrology.
