My wife Michele and I recently watched a Nova episode: Asteroid:
Doomsday or Payday? and I noticed that instead of the usual Nova
rendering of most measures in non-SI units, many measures were only
SI, like meters and kilometers with no equivalents given in yards,
feet or miles. Of course I would have preferred the whole episode in
exclusively SI units, but some "experts" still used exclusively non-SI
measures. Some gave measures then parenthetically gave their
equivalents.
Today we watched Fareed Zakaria (GPS) interview Elon Musk of Space X
about many new innovations, including his Hyperloop.
I noticed that Figure 12

uses exclusively SI measures. Have a look at the graphic.
Even though I would like to see the United States complete metrication
at a faster pace, I think this slow, incremental creep seems to be how
many Americans are becoming accustomed to our inevitable slide toward
abandoning non-SI measures.
