Yesterday Sheryl was watching an American TV show on a streaming service. The show is called something like "Metal Shop", and is a competition where contestants make items from metal. One contestant explained that she was turning a work item slowly, at "5 RPMs per minute". RPM is an acronym for Revolutions Per Minute, so she claimed that she was turning it at 5 revolutions per minute per minute. Also, RPM does not have a plural; one should say "5 RPM". Of course, there is such a thing as RPM per minute; it is a measure of the rate of change of RPM; after one minute rotation rate would be 5 RPM, and after 2 minutes it would be 10 RPM. That, however, is not what the contestant meant. I would expect that "RPM" would be part of her expert vocabulary; even if her language skills are not great in all domains, they should be good in her area of expertise. | |
