The Revised SI for the Kilogram

History of SI • First milestone • Creation of the decimal metric system at the time of the French Revolution • Deposition of two platinum standards representing the metre and the kilogram, on 22 June 1799, in the Archives de la République in Paris • Signing of the Metre Convention on 20 May 1875 • Created the BIPM and established the CGPM and the CIPM • Work began on the construction of new international prototypes of the metre and kilogram. • In 1889 the 1st CGPM sanctioned the international prototypes for the metre and the kilogram. • Together with the astronomical second as the unit of time, these units constituted a three-dimensional mechanical unit system similar to the CGS system, but with the base units metre, kilogram, and second, the MKS system. Changes in measurement standards (not new) Mass Redefinition of SI • Link to fundamental constants of nature • More accurate over time 1889 https://www.bipm.org/en/measurement-units/rev-si/ Which units will be redefined? Why? • The revision of the SI will ensure that the SI continues to meet the needs of science, technology, and commerce in the 21st century. -

Introducción: Α a success story of a proud and a purposeful city≅ The Financial Times (1999) ha calificado el proceso urbano reciente de Barcelona como Αuna historia de éxito de una ciudad orgullosa y tenaz≅; probablemente es un buen resumen del esfuerzo importante realizado por la ciudad, y también por la región de Cataluña, para mejorar la calidad de vida y la competitividad económica. Estas observaciones son consecuencia del reciente premio de los arquitectos británicos (RIBA) a los valores arquitectónicos y urbanísticos desarrollados por la ciudad durante las últimas dos décadas. El premio fue recibido por el alcalde actual desde 1997, Joan Clos, acompañado por Narcís Serra, primer alcalde democrático (1979-1982), el alcalde del período 1982 a 1997 (Pascual Maragall), el Director de Urbanismo desde 1982 a 1986 (Oriol Bohigas) y el Director técnico del Holding Olímpico desde 1987 a 1993 (Josep Acebillo), como los principales actores del proceso urbano de este largo período. -

Submission from Pat Naughtin
Inquiry into Australia's future oil supply and alternative transport fuels Submission from Pat Naughtin Dear Committee members, My submission will be short and simple, and it applies to all four terms of reference. Here is my submission: When you are writing your report on this inquiry, could you please confine yourself to using the International System Of Units (SI) especially when you are referring to amounts of energy. SI has only one unit for energy — joule — with these multiples to measure larger amounts of energy — kilojoules, megajoules, gigajoules, terajoules, petajoules, exajoules, zettajoules, and yottajoules. This is the end of my submission. Supporting material You probably need to know a few things about this submission. What is the legal situation? See 1 Legal issues. Why is this submission needed? See 2 Deliberate confusion. Is the joule the right unit to use? See 3 Chronology of the joule. Why am I making a submission to your inquiry? See: 4 Why do I care about energy issues and the joule? Who is Pat Naughtin and does he know what he's talking about? See below signature. Cheers and best wishes with your inquiry, Pat Naughtin ASM (NSAA), LCAMS (USMA)* PO Box 305, Belmont, Geelong, Australia Phone 61 3 5241 2008 Pat Naughtin is the editor of the 'Numbers and measurement' chapter of the Australian Government Publishing Service 'Style manual – for writers, editors and printers'; he is a Member of the National Speakers Association of Australia and the International Association of Professional Speakers.

The Case of the International Bureau of Weights and Measures (BIPM) the Case of The
International Regulatory Co-operation and International Regulatory Co-operation International Organisations and International Organisations The Case of the International Bureau of Weights and Measures (BIPM) The Case of the The International Bureau of Weights and Measures (BIPM) is the intergovernmental organisation through which Member States act together on matters related to measurement International Bureau of science and measurement standards. Together with the wider metrology community, as well as other strategic partners, the BIPM ensures that the measurement results from Weights and Measures different states are comparable, mutually trusted and accepted. The BIPM provides a forum for the creation and worldwide adoption of common rules of measurement. The international system of measurement that the BIPM co-ordinates worldwide underpins the (BIPM) benefits of international regulatory co-operation (IRC): increased trade and investment flows and additional GDP points; gains in administrative efficiency and cost savings for governments, businesses and citizens; and societal benefits such as improved safety and strengthened environmental sustainability. Accurate measurements are specifically necessary to regulators and legislators for establishing and enforcing regulatory limits. This case study describes how the BIPM supports international regulatory co-operation (IRC) – its institutional context, its main characteristics, its impacts, successes and challenges.
