AW: [ RadSafe ] SI; Now or never?

[Rainer.Facius at dlr.de]

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.

Betreff: RE: [ RadSafe ] SI; Now or never?



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... :-).
