However we should note that both mW and MW are in general use in engineering. The power of my hearing aid is measured in milliwatts and the power of the train that I used when travelling to London yesterday is measured in megawatts.

Like cc (centi-centi) or KPH (Kelvin Pascal Hertz) or kph ( kilo pico hour) Mark Oh, and a 5K race would be a 5 Kelvin race.

As Pierre rightly point out, 1 MG = 1hT or, as per the Wikipedia table at https://en.wikipedia.org/wiki/Metric_system , 1 G = 10^-4 T. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Pierre Abbat Sent: 15 May 2014 10:43 To: U.S. Metric Association Subject: [USMA:53819] Re: MG On Tuesday, May 13, 2014 16:36:34 [email protected] wrote: Dr Patricia Weeks here at the Salem Clinic printed out a perscription for my wife today for 150 MG of a particular medication. Astonished, I pointed out to Dr Weeks that when the M is capitalized, it means mega, which in this case, would means 150 megagrams, or 150 metric tons of medication. MG is not megagram. It is megagauss (1 MG=1 hT). Pierre --ve ka'a ro klaji la .romas. se jmaji ----- End message from Martin Vlietstra <[email protected]> ----- David Pearl www.MetricPioneer.com 503-428-4917
