ਨੋਟ[ਸੋਧੋ]

  1. 'SI' is an initialism of Système international, which is an abbreviated form of its full French name Système international d'unités,[1]: 165  which literally means 'International System of Units'. By Resolution 12 of the 11th CGPM (1960), the international abbreviation of the name of the system is: SI.[1]: 165 
  2. When we say 'SI system', we are basically saying the word 'system' twice: 'International System system' (note that 'SI' stands for the French name Système international, which literally means 'International System'). This is a type of linguistic redundancy called pleonasm. Some examples of such pleonastic usage include the list of 'alternate titles' in the Encyclopedia Britannica article on the SI,[3] the last paragraph in an editorial in the journal Nature,[4] and the footnote 1 to Table 5 in the style manual of the International Astronomical Union.[5]
  3. In a decimal system, different units for a given kind of physical quantity are related by factors of 10, so that, within such a system, unit conversions involve the simple process of moving the decimal point to the right or to the left.[8] So instead of relations like 1 mile = 1,760 yards, as in the imperial and US customary measurement systems (which are not decimal), in the SI (which is decimal) 1 kilometre = 1000 metres. Here the kilometre is comparable in size to the mile (1 km0.6 mi) and the metre to the yard (1 ਮੀਟਰ1.1 ਗਜ਼).
  4. Or one of its decimal multiples or submultiples, like the centimetre.
  5. Or one of its decimal multiples or submultiples, like the gram.
  6. Or one of its decimal multiples or submultiples, like the gram-force.
  7. A metric system of units is any system of weights and measures that is decimal[lower-alpha 3] and based on the metre[lower-alpha 4] as the unit of length and either the kilogram[lower-alpha 5] as the unit of mass or the kilogram-force[lower-alpha 6] as the unit of force.
  8. From French: Conférence générale des poids et mesures.
  9. 19 ਜਨਵਰੀ 2021 ਤੱਕ .
  10. The latter group includes economic unions such as the Caribbean Community (CARICOM).
  11. This is an international organization with[lower-alpha 9] 63 member states and 39 Associate States and Economies of the General Conference.[lower-alpha 10][12] It was established in 1875 under the terms of the Metre Convention.[11][13]
  12. It shall be lawful throughout the United States of America to employ the weights and measures of the metric system; and no contract or dealing, or pleading in any court, shall be deemed invalid or liable to objection because the weights or measures expressed or referred to therein are weights or measures of the metric system. (15 U.S.C. § 204)
  13. Here 'official status' means that the SI is recognized in some way by the laws and regulations of the country. In many countries, this means that using the SI units is mandatory for most commercial and administrative purposes (e.g. in the European Union). On the other hand, when it comes to the US, 'official status' means that federal law specifically allows, but doesn't require, the SI units to be used.[lower-alpha 12] In fact, federal law even states that it is the declared policy of the United States to designate the metric system of measurement as the preferred system of weights and measures for United States trade and commerce (15 U.S.C. § 205b).
