Don't turn this into one of your famous "You are anti-American" bullshit threads.
Why would anyone need to know how many inches are in a mile?
Dunno, but in the case that someone does need to know it, how difficult it is to multiple in your head this equation:
12 inches = 1 foot
3 feet = 1 yard
1760 yards = 1 mile
Do the calculation IN YOUR HEAD:
12 x 3 x 1760
I can tell you that a very very small section of the population would know that there 63,360 inches in a mile.
Can you tell me how many centimetres are in a kilometre?
Easy to calculate in your head
100 centimetres = 1 metre
1000 metres = 1 kilometres
100 x 1000
Therefore, 100,000 centimetres in a kilometre.
The metric system is a piss easy way to break large units of length, mass, etc into smaller units, whereas the imperial is cumbersome and harder to do that.
What do I care?
I couldn't give a fat rat's if the Yanks are behind the rest of the world in this.
Education is no problem, because as long as kids are taught in school their multiplication tables, they will have no problem picking this up. Like I said, only a total moron would have problems in dealing with the metric system (in that case, Alabama can stick with the imperial system).
But why, may I ask is there such resistance to change?
Could it be because the metric system is a system devised by the French?
