In the '50s and '60s, slow single engine aircraft had their speed indicator in mph instead of knots (which is not a SI unit); simply because the number in mph was higher than the number in knots, and made the airplane seems to fly faster.

I wonder why you want to argue about the fact I just identified.

The difference is approximately a 15% higher indicated number when in mph. For marketing purpose, it is 15% increase, at no cost.

Just like when hard drive manufacturers decided to change the definition of 1 KB = 1024 bytes to 1 KB = 1000 bytes, and when TV manufacturers switched from actual diagonal screen size measurements to the "class" designation that is half an inch smaller in reality. Or, for that matter, advertising 2160p UHD as "4K" which people assume means 4000p. Instant increase in advertised figures at no extra cost!

Speeds in km/h are higher than equivalent speeds in mph, so yes, they sound more dramatic.

It's like saying "I survived getting shocked by TWELVE THOUSAND millivolts!"

This actually happened to me:
 YVR Terminal: Please expedite your climb to 3000
 Me: You realize we're in a 150, right ?

I clawed my way up a bit over 10,000' MSL in the winter about 25 years ago in a J5-A.  Took the better part of an hour to get there, and the last 1500 feet or so were at a REALLY glacial rate.  Was headed into a rather stiff west wind, too, and often wonder what people on the ground must have thought seeing as I only traveled a few miles horizontally over what must have been 45 minutes.  Fixed wing planes don't typically hover...

Maybe we should rename it the Myanmar System of Units...   :-DD

TimFox:
With proper grammar, we need an adjective in front of "system".  Try "Burmese system of units".
