Dual measurement systems causes confusion and waste the world round, in tools and factories everywhere. Not to mention truly silly screwups, like the now-legendary NASA fuckup
, and don't tell me those people didn't have enough education.
The imperial system is simply unnecessarily confusing, and that is that. Do you know what the imperial unit of mass is, or how many kilograms that converts to?
Also, pounds is weight, which means it has to be compared to Newtons. You're all getting F's in my physics class, not being able to convert basic units.
Now the trick is, those same duplicate parts, tools, factory settings and such are the very things holding back the transition. Changing the measurements and tolerances of all those machines and devices, all the paperwork filed for surveying going back hundreds of years, and most importantly changing everyone's intuitive sense of what's long and short, what's hot and cold, what's heavy and light, etc., all takes time and money. Tons of money, actually, which is why the last US changeover was supposedly rejected.
No one in their right mind would argue that the Imperial system is easier to use. Base 10 conversions for everything is so simple one can do it in their head, but if I ask you how many inches are in 473 miles, I bet you have to bust out the calculator.
Before you say that busting out the calculator is no problem, keep in mind that a) someone has to make those calculators, and b) the calculator is only as good as what you punch in it. Not to mention complexities like Joules, which is one Newton-Meter, but something like a BTU is some extremely odd number of foot-pounds. Try working those
out in metric and standard and tell me which you prefer.
Personally, I'd love to see a metric switchover. Most of my classmates seemed to agree. It just takes time.
I'm doing my part by trying to develop a sense of distance in metric, and a similar sense of weight and temperature.
Look, you can't make me speak in a logical, coherent, intelligent bananna.
