These devices are often recalibrated in a national metrology laboratory. [5], The three organisations were set up under the treaty. [1] It is commonly referred to by its French initials of BIPM and it is one of three such organizations established to maintain the International System of Units (SI) under the terms of the Metre Convention (French: Convention du Mètre). information, see the section International aspects of the SI. Member states would have regular meetings to discuss developments in measurement technology.  Turkey (1875)[n1 1][n1 10]

It also drafts the SI standard which is called the SI Brochure.[8][9]. They take part on the CIPM MRA program. CS1 maint: multiple names: authors list (.  Tunisia (2012) ampere The CIPM comes under the authority of the CGPM. As of 29 March 2010, there are 54 Member States of the BIPM.[4].

It provides laboratory services for the CGPM and CIPM. These devices might be petrol pumps. The BIPM has its headquarters at the Pavillon de Breteuil, Sèvres, France (close to Paris). In February 2014 there were ten such committees. unification of physical measurements. The short name was "SI".  Zambia (2010) Membership lapsed 1957. They might be weighing scales.

It is the "international" They must all come from different countries. [19], Albania (2007)  Portugal (1876)[n1 1], Romania (1884) These members are well-known measurement experts who are elected by the CGPM. General Conference on Weights and Measures (CGPM, Conférence Générale des Poids et Mesures).

 Bulgaria (1911)  Norway (1875)[n1 1][n1 7]

 Jamaica (2003)  Oman (2012), Panama (2003)

Nine of the committees are dedicated to special types of measurement such as Electricity and Magnetism, Length, Photometry and Radiometry, Thermometry and Time and Frequency.  South Africa (1964) These organizations include International Organization for Standardization (ISO) and National Institute of Standards and Technology (NIST).  Canada (1907) It suggests modifications The BIPM carries out measurement-related research, organizes international comparisons of national measurement standards, and performs calibrations for member states.

 Netherlands (1929) International Bureau of Weights and Measures (BIPM), international organization founded to bring about the unification of measurement systems, to establish and preserve fundamental international standards and prototypes, to verify national standards, and to determine fundamental physical constants.  Mongolia (2013)

[4]:75-76, The organization set up by the treaty was the International Bureau of Weights and Measures. The metric system was developed in France in the 1790s. [1], In 1875 France invited representatives to Paris to discuss the matter. It advises the CGPM and supervise the BIPM.  Greece (2001), Hungary (1925)  Namibia (2012) Other countries are associate members. Its abbreviation is BIPM. International Bureau of Weights and Measures official site: International Bureau of Weights and Measures, The General Conference on Weights and Measures (CGPM), The International Committee for Weights and Measures (CIPM), International Organization for Standardization (ISO), National Institute of Standards and Technology (NIST), International Union of Pure and Applied Physics, Institute for Reference Materials and Measurements, Text of the current version of the Convention (in French and English), English translation of the original text of the Convention, "Message from the President of the United States, transmitting a report of a metric convention between the United States and certain foreign governments, signed at Paris on the 20th of May, 1875", "Outlines of the evolution of weights and measures and the metric system", "Bureau international des poids et mesures - International Bureau of Weights and Measures - (BIPM)", "General Conference on Weights and Measures", "Criteria for membership of a Consultative Committee", Bureau International des Poids et Mesures, "Resolutions of the CGPM: 8th meeting (3-10 October 1933)", "NASA Explains Why Clocks Will Get an Extra Second on June 30", "NASA Details Earthquake Effects on the Earth", "Members of the International Committee for Weights and Measures (CIPM) 1875-1977", Procedure for a State or Economy to become an Associate of the General Conference, The Democratic People's Republic of Korea, "BIPM – Dominican Republic [Member State]", https://simple.wikipedia.org/w/index.php?title=Metre_Convention&oldid=6544733#BIPM, Creative Commons Attribution/Share-Alike License. Its abbreviation is "CGPM".  South Korea (1959) It has There would be six base units. The Convention was signed in Paris on 20 May 1875 by representatives of 17 nations. [11] The use of standard gravity in force and pressure definitions resulted in more units of measure being defined than were necessary. Its abbreviation is CIPM.

All of this came together to produce one of the world’s oldest international institutions: The International Bureau of Weights and Measures (BIPM). Many measuring devices need to be recalibrated at regular intervals.  China (1977)  Indonesia (1960)  Italy (1875)[n1 1]  Peru (2009)[n1 11][18]

[13]:110[14] The BIPM described SI as "the modern metric system".[13]:95. [12] The CIPM reported back and in 1954 the 10th CGPM decided to set up a new system of units.  Caribbean Community (2005) Since then both English and French have been used.  Slovenia (2003)  Israel (1985) Mathematics. In 1921, the Metre Convention treaty was revised by the 6th CGPM to extend the scope and responsibilities of the BIPM to other fields in physics. The Case of the International Bureau of Weights and Measures (BIPM) The International Bureau of Weights and Measures (BIPM) is the intergovernmental organisation through which Member States act together on matters related to measurement science and measurement standards. The International Committee for Weights and Measures was set up under the Metre Convention as an organ of the BIPM. Until 1988 all reports of meetings were only published in French.  Pakistan (1973)  Georgia (2008), Ghana (2009)

[1]:xx Official communications between the BIPM and France are conducted via the French Foreign Ministry. Other refinements include small changes to details of definitions.  Philippines (2002)  Australia (1947) Other members of the committee are appointed by other organizations. International Committee for Weights and Measures (CIPM). metrology institute, and operates under the exclusive supervision These were the metre, kilogram, second, ampere, degree Kelvin (later renamed kelvin), and candela.  United Kingdom (1884) It combines, analyzes, and averages the official atomic time standards of member nations around the world to create a single, official Coordinated Universal Time (UTC). The bar would be used as a standard for the metre. Three organisations would be set up to administer the treaty. The BIPM is an inter-governmental organization that is responsible for harmonizing systems of measurement across the world.
