[ RadSafe ] SI; Now or never?

[Rogers Brent]

Accidents such as the one you described are exactly why the US should NOT go
SI.   Most professionals have little difficulty working in both systems.
Most technologists have somewhat more difficulty, and most doctors that have
been prescribing mCi amounts for years truly can't cope.  Imagine the
potential for accidents that involve real people (not spaceships) during the
turnover.  

BTW, as I notice you work for the German Aerospace Center, perhaps you can
explain the splendid, deplorable, quite expensive failure of the Beagle 2?

One of the more spectacular outgrowths of your splendid isolation was the
deplorable loss ( after 1990! ) of quite an expensive Mars satellite - wrong
or forgotten meter to feet (or km to miles) conversion, if I remember
correctly.

I suspected something like that :-).
My guess is that the radiation units are those taking about the
least effort to switch. I doubt there are many people who
grew up in the US and think millimeters rather than fractions
of an inch, litres rather than gallons/pints (whatever....:-),
kmph rather than mph etc...
 The chip industry has made the move - they just specify
dimensions both in millimters and inches, and, well, we all
use Volts, Amps, Watts etc.
 I do wonder how it is with temperatures. Those of the
listmembers doing lab work must be used to degree Celsius (and/or
Kelvin), however, when it comes to weather - do they still think
Fahrenheit? My guess is they have developed a precise
calculator to do the conversion a long time ago (I have
to struggle every time I am confronted with degree F,
although evenually I manage it... :-).
