The article is very interesting, however, subscribers to this mailing list should have a look at the Comments section which follows it. The first comment reminds the author that "microamps" should be written as "µA" and not "uA". Subsequent comments discuss: * The history of metric electrical units, * The validity of calling "cycles per second" a metric unit, * The difficulty of finding symbols such as "µ" on a Windows PC, * Problems writing metric units using SPICE software (Something Something In-Circuit Emulator) * The inappropriate values needed for some derived units to represent measurements met in the real world, (specifically, kilopascals,) * "Specialty" units needed to overcome the problem of derived units with large values. It’s fun to read and I hope it leads to some discussion here. There is a post on Reddit about this article, and comments will be here: https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.reddit.com%2Fr%2FMetric%2Fcomments%2Fs8uxiz%2Fa_web_article_on_electronic_amplifiers_leads_to%2F&data=04%7C01%7Cusma%40lists.colostate.edu%7Cbff596610bf742aef47f08d9dc6b6c1b%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637783176379130369%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=taJdtaFtf0aTYUQlQ9XYPpOH78pIerf7UkLnN1YUbGQ%3D&reserved=0 Best wishes, Peter Goodyear, Melbourne, Australia e-mail: [email protected]<mailto:[email protected]>
