Weights and measures

The above dream was scaled up in exact portions, as it was her first Her next dream had some variations to weights and measures, plus a longer reaction time... 

Regulation Outside the United States. Each country estabhshes its own weights and measures requirements. The majority of these are based on the recommendations of the Organisation Internationale de Miitrologie Liigale (OIML), ia Paris. K76-1 is the OIML equivalent of Handbook 44 it uses accuracy classes and an acceptance tolerance stmcture similar ia many ways to Table 1 (8). 

Variations in the Force Due to Gravity. The mass of an object is the quantity of matter ia the object. It is a fundamental quantity that is fixed, and does not change with time, temperature, location, etc. The standard for mass is a platinum—iridium cylinder, called the International Kilogram, maintained at the International Bureau of Weights and Measures, ia Snvres, France. The mass of this cylinder is 1 kg by definition (9). AH national mass standards are traceable to this artifact standard.

The International Bureau of Weights and Measures, BIPM (Parc de Saint-Cloud, France) is described in Appendix X2 of Ref 4. This bureau operates under the exclusive supervision of the International Committee for Weights and Measures (CIPM). 

Mass. The unit of mass is the kilogram and is the mass of a particular cylinder of Pt—Ir alloy which is preserved in France by the International Bureau of Weights and Measures.

This international prototype, adopted by the 1st and 3rd CGPM in 1889 and 1901, is a particular cylinder of platinum—iridium kept at the International Bureau of Weights and Measures near Paris. It is the only base unit still defined by an artifact.

This Inspiring teacher and tireless experimenter was so deeply concerned over social issues that he resigned his professorship rather than obey an order to cease interfering with affairs of government. He made enemies by supporting liberal movements and even defied the Czar s wishes by refusing to cut lus hair. Nevertheless, he won the appointment as Director of the Bureau of Weights and Measures. 

For scientific work the fundamental standard of mass is the international prototype kilogram, which is a mass of platinum-iridium alloy made in 1887 and deposited in the International Bureau of Weights and Measures near Paris. Authentic copies of the standard are kept by the appropriate responsible authorities in the various countries of the world these copies are employed for the comparison of secondary standards, which are used in the calibration of weights for scientific work. The unit of mass that is almost universally employed in laboratory work, however, is the gram, which may be defined as the one-thousandth part of the mass of the international prototype kilogram.

SI Units—The International System of Units as defined by the General Conference of Weights and Measures in 1960. These units are generally based on the meter/kilogram/second units, with special quantities for radiation including the becquerel, gray, and sievert. 

The National Institute of Advanced Industrial Science Technology (NIAIST) began operations on April 1, 2001. The NIAIST included the Weights and Measures Training Institute in addition to the 15 other institutions already existing within AIST. The NIAIST is Japan s largest public research organization. 

The SI unit of the amount of substance n is the mole. Curiously, the SI General Conference on Weights and Measures only decided in 1971 to incorporate the mole into its basic set of fundamental parameters, thereby filling an embarrassing loophole. The mole is the amount of substance in a system that contains as many elementary entities as does 0.012 kg (12 g) of carbon-12. The amount of substance must be stated in terms of the elementary entities chosen, be they photons, electrons, protons, atoms, ions or molecules.
