I'm a professional pilot, and I fly large helicopters in Nigeria on a Six-Week on, Six-Week off schedule. In the aviation world, we have to use not two, but FOUR systems of measurement.
Altitudes are expressed in Feet. Speeds and distances are expressed in Nautical Miles. Runway visibilities are expressed in EITHER meters or feet, depending on where you are operating from (and that is not consistent). Fuel, again depending on the location, is expressed in Gallons, Liters, or imperial pounds. Engine instrument pressures may be indicated in PSI or Bars...depending on where manufactured. Barometric pressures are expressed in two ways as well, and some altimeter manufacturers have been making their instruments to indicate both. Confusing?? You better believe it!
Even NASA has had problems with this. A number of years ago, a Mars Mission ended in a crash because someone at NASA had used Imperial measurements instead of Metric. The lander was lost during descent as a result, at a loss of almost $1 Billion.
I'm an advocate of moving entirely to the metric system... even in the air. We were supposedly supposed to have completed this conversion by the mid-eighties, just as other countries have done in their past, but politics have once again intervened, and our education system has failed its children by continuing to press for the buggy whip, instead of the engine.
There has been many a debate on Metric vs Imperial since I registered on the FOG back in early May this year.
You have summed up the reasons and need for a universal system exceptionally well through your NASA and aviation examples. However real change will still take time. Eg in Australia we have been officially metric since around 1972, but still people refer to 4x2inch timber, 32inch televisions, 54 inch mower decks an so on. Some of this is history, a persons age or because one of the major universal market places [ie USA] is yet to convert.
Other posts have explored the reasons and having read them I make no claims of superiority, each to their own, or what works for them; however your examples do highlight the need for a convention at international levels.
