(International Conference for Determination of Electrical Units) Held 16–26 October. Was motivated by a resolution from the 1881 International Electrical Congress. A verbal transcript of the conference was published. 1884 in Paris International Conference for Determination of Electrical Units 1889 in Paris International Congress of Electricians Held 24–31 August, in connection with Exposition universelle de 1889. About 530 participants from at least 11 countries. Adopted several units, including practical units of power (watt) and work (joule), where 1 watt = 107 erg/second, and 1 joule = 107 erg. Considered practical magnetic units, but did not make any resolutions or recommendations. 1891 in Frankfurt Held 7–12 September, in connection with the International Electrotechnical Exhibition (Die Internationale Elektrotechnische Ausstellung 1891), organized by Elektrotechnische Gesellschaft. Galileo Ferraris was a vice-president at the conference. There were 715 participants (473 from Germany and 243 from other countries, including Austria, United Kingdom, USA, and France). An official report of the conference was published. Papers and discussions were organised in five main areas: Theory and Measuring Science; Strong Current Technology; Signalling, Telegraphy, and Telephony; Electrochemistry and Electric Current Applications; and Legislation to Mediate Conflicts between Cities around different currents used for electric lights, telephones, and telegraphs. 1892 in Edinburgh Held in connection with the British Association for the Advancement of Science annual meeting 1896 in Geneva Held 4–9 August, in connection with the . Insufficient and late communication about the organization of the Congress hampered widespread participation, so that the conference had about 200 participants, mostly from Switzerland, Austria, Germany and Belgium. Topics for discussion were magnetic units, photometric units, the long-distance transmission of power, the protection of high-tension lines against atmospheric discharge, and the problems and challenges of electric railway operation. International Electrotechnical Congress 1908 in London International Conference on Electric Units and Standards. Held in October. Organized by the Commission on Electric Units and Standards of the International Electrotechnical Commission Formal adoption of the "international units" (e.g., international ohm, international ampere), which were proposed originally in the 1893 meeting of the International Electrical Congress in Chicago. 1911 in Turin Held 10–17 September, organized by and the Italian Electrotechnical Committee of the International Electrotechnical Commission 1915 in San Francisco Was to be held 13–18 September, and organized by the American Institute of Electrical Engineers, but was cancelled because of the outbreak of World War I.
