International Conference on Weights and Measures

The system of units used worldwide today is the International System of Units, in French, Systeme Inter national d Unites (SI). The Bureau International des Poids et Mesures (BIPM) adopted the SI system at its 11th General Conference on Weights and Measures (Conference Generate des Poids et Mesures -CGPM-) in 1960. 

The General Conference on Weights and Measures (CGPM) meets every 4 years and makes additions to, and changes in, the international system of units (SI).3 A select group of 18 internationally recognized scientists from the treaty nations is the International Committee of Weights and Measures... 

In 1960, the eleventh General Conference on Weights and Measures recommended the International System of Units (Systeme International d Unites), abbreviated as SI units, for use in science SI units are essentially the rationalized mks system of units. Relations between SI units and Gaussian units are given in Table A.4 of the Appendix. Table A.5 allows one to convert equations from SI to Gaussian units. 

In 1960 the International General Conference on Weights and Measures adopted an improved form of the metric system, The International System of Units (SI). The units of mass, length, and time are the kilogram (kg), meter (m), and second (s). The following prefixes are used for fractions and multiples ... 

SI (Systeme International, International System of Units)—metric-based system of weights and measures adopted in 1960 by the 11th General Conference on Weights and Measures, in which 36 countries, including the U.S., participated. SI consists of seven basic units ... 

Despite imaginative suggestions by Isaac Newton and others, the Celsius centigrade system became the international scientific standard, prevailing for about two centuries. However, in 1954 the Celsius scale was replaced (at the 10th General Conference on Weights and Measures) by the. vmg/e-refcrence ideal gas temperature scale described in the text. 

The General Conference on Weights and Measures updated the metric system in 1960 and renamed it the International System of Measurements. The system is commonly referred to as SI, which is short for the French name, Le Systeme International d Unites. Scientists from all around the world have adopted SI, and there has been a push in many countries to convert the general population to the SI units. 

International System of Units (SI) - The unit system adopted by the General Conference on Weights and Measures in 1960. It consists of seven base units (meter, kilogram, second, ampere, kelvin, mole, candela), plus derived units and prefixes. [1]... 

SI Abbreviation for the worldwide standard prepared by the International System of Units. SI is from the French name Le Systeme International d Unites. This standard gives guidance for application of the modernized metric system developed and maintained by the Group Conference on Weights and Measures (CGPM for the official French name Conference Generale des Poids et Mesures). The SI abbreviations were adopted by the eleventh CGPM in 1960. See Appendix B, Conversion Tables decimal number system measurement meter number marker.
