	Weights And Measures - LoveToKnow 1911
		Of the metric units international definitions have been stated as follows: (a) The unit of volume for determinations of a high degree of accuracy is the volume occupied by the mass of 1 kilogram of pure water at its maximum density and under the normal atmospheric pressure; this volume is called litre.
		The two standards, the cubic inch and the cubic decimetre, may not be strictly comparable owing to a difference in the normal temperature (Centigrade and Fahrenheit scales) of the two units of extension, the metre and the yard.
		The value of this intensity is equal to that of the force of gravity at the Bureau International, Paris (at the level of the Bureau), divided by 1.000332; a co-efficient which allows for theoretical reduction to the latitude 45° and to the level of the sea.

	International Committee for Weights and Measures - Wikipedia, the free encyclopedia
		The International Committee for Weights and Measures is the English name of the Comité international des poids et mesures (CIPM, sometimes written in English Comité International des Poids et Mesures).
		Its principal task is to ensure world-wide uniformity in units of measurement and it does this by direct action or by submitting proposals to the General Conference on Weights and Measures (CGPM, Conférence générale des poids et mesures).
		The CIPM meets annually at the International Bureau of Weights and Measures (BIPM, Bureau international des poids et mesures), and discusses reports presented to it by its Consultative Committees.

		Synoptic diagram of the international organisation of metrology
		The BIPM, whose headquarters is at the Pavillon de Breteuil in Sèvres, is a scientific metrology laboratory whose main mission is to guarantee the uniformity of measurements (both physical and chemical) throughout the world.
		The Mutual Recognition Arrangement (MRA) was drawn up by the Comité International des Poids et Mesures (CIPM) under the authority given to it by the Member States of the Metre Convention and signed in October 1999 by the NMI directors.

	International Bureau of Weights and Measures - Wikipedia, the free encyclopedia
		It is based at the Pavillon de Breteuil in Sèvres, France, where it enjoys extraterritorial status.
		The task of the BIPM is to ensure world-wide uniformity of measurements and their traceability to the International System of Units (SI).
		It does this with the authority of the Convention du Mètre, a diplomatic treaty between fifty-one nations (as of 2005), and it operates through a series of Consultative Committees, whose members are the national metrology laboratories of the Member States of the Convention, and through its own laboratory work.

	Metric Convention of 1875
		The operation of the international bureau shall be under the exclusive direction and supervision of an international committee of weights and measures, which latter shall be under the control of a general conference for weights and measures, to be composed of the delgates of all the contracting governments.
		The entire expense of the construction and outfit of the international bureau of weights and mesasures, together with the annual cost of its maintenance and the expenses of the committee, shall be defrayed by contributions from the contracting states, the amount of which shall be computed in proportion to the actual population of each.
		The French section of the international commission of 1872 shall continue to have charge of the labors entrusted to it in the construction of the new prototypes, with the co-operation of the international committee.

	Historical and international aspects of the SI
		The SI was established in 1960 by the 11th General Conference on Weights and Measures (CGPM, Conférence Générale des Poids et Mesures).
		The CGPM is the international authority that ensures wide dissemination of the SI and modifies the SI as necessary to reflect the latest advances in science and technology.
		The Convention, modified slightly in 1921, remains the basis of all international agreement on units of measurement.

	International Relations \| NRC-INMS
		With international trade agreements now demanding demonstrated equivalence between the measurement standards and accreditation systems of buyer and seller nations, metrology has become vital to the regulation of trade and in the resolution of trade disputes.
		INMS is active in these organizations and in approximately 150 international committees under the auspices of global bodies such as the Comité International des Poids et Mesures (CIPM).
		The reliability of the international measurement system depends on continued effort by each National Metrology Institute (NMI) to base its measurements and measurement uncertainties on universally accepted units, usually those of the SI, and to compare its measurements with those of other NMIs to establish their mutual equivalence.

		The Bureau International des Poids et Mesures (BIPM, International Bureau of Weights and Measures) was set up by the Convention du Mètre signed in Paris on 20th May 1875 by seventeen States.
		It is responsible for establishing and maintaining the fundamental standards for measurements of the principal physical quantities, organising comparisons of national and international standards, co-ordinating the corresponding measuring techniques and determinations relating to the fundamental physical constants that are involved in the above-mentioned activities.

	Re: WHY ON THE KELVIN TEMPERATURE SCALE IS THERE NO DEGREE SYMBOL?
		As well as founding the BIPM and laying down the way in which the activities of the BIPM should be financed and managed, the Metre Convention established a permanent organizational structure for member governments to act in common accord on all matters relating to units of measurement.
		The International System of Units (SI) The 11th Conférence Générale des Poids et Mesures (1960) adopted the name Système International d'Unités (International System of Units, international abbreviation SI), for the recommended practical system of units of measurement.
		This resulted in the curious situation that thermodynamic temperatures were defined in quite a different way to International Practical Temperatures (in which two fixed points were used for the definition of the degree Kelvin, and whose unit was also the degree Kelvin).

		BIPM is headquartered in the Pavillon de Breteuil, a historic and beautiful chateau overlooking the Seine at Sèvres, on the outskirts of Paris.
		CCU is responsible for advising the International Committee on changes and developments to be made to the International System of Units (SI), and particularly on choosing the standards that define the base units of the SI.
		Another aspect of the work is its international nature: the need for us all to speak the same language of science so that we understand one another without ambiguity and use internationally agreed upon names and symbols for the quantities and units involved.

		SPRING Singapore is also a signatory of the CIPM MRA (Mutual recognition of national measurement standards and of calibration and measurement certificates issued by national metrology institutes) since 1999.
		By signing the CIPM MRA and successfully completed the strict assessment of our quality system and technical competency by our international peers, our Calibration and Measurement Capabilities (CMCs) have been internationally recognized and can be found in the BIPM database for CMCs.
		At a meeting held in Paris on 14 October 1999, the directors of the national metrology institutes (NMIs) of thirty-eight MemberStates of the Metre Convention and representatives of two international organizations signed a Mutual Recognition Arrangement (CIPM MRA) for national measurement standards and for calibration and measurement certificates issued by NMIs.

		NC-IUB and JCBN are therefore asking IUB and IUPAC to apply to the Comité international des poids et mesures (International Committee of Weights and Measures) to "approve the name 'dalton' (symbol: Da) as an alternative to the name 'atomic' mass unit' (symbol: u)".
