Some of those are a bit of grey area, for instance the UK is marked non-metric even though all products to be sold have to have their weight/size etc. marked in metric units. The metric system is taught in all schools and used in all science work, infact the only official use of the imperial system i can think of is in distances on road signs and speed limits. Bearing that in mind, US you’re pretty much on your own.
The advantage of being culturally dominant within your own borders…
yeah, well the US isn’t as bad as the UK in some ways, though. for instance not only do they measure weight in pounds, but they also use them as their currency!!
What are the colors/dates supposed to represent?
pssshh…everyone knows that it’s 212. and come on, that’s a perfectly round and natural number. 
I imagine it represents when the countries switched over the the metric system.
Hardly a mistake but there are 14 pounds in a stone. Saying that there MIGHT be an integer number of stones in a pound (12, 16, 20) just reverses the order of the units. Normally one states this as pounds per stone.
god why does that system have to be so complicated !!
metric is by far the best, it’s easier to use, easier to understand, and better for smaller measurements. we can just say “oh yeah, it’s 1.5mm thick”, whereas imperial guys would say “oh yeah, it’s 1/12ths thick” (im not sure what 1?12ths are but you get the point)
its also a heck of a lot quicker not to use proper punctuation or grammer in a sentence properly and people like yourself still use it properly
I really like the metric system even though I live in the US. I wonder when/if we’ll ever get rid of the imperial system…
Also, what makes a country not applicable to the metric system? I lived in Egypt for two months and they seemed fairly metric to me.
Ok, now make a same map for mobile-phone standards…
You will have a big black spot in North America and the only other black spot will be… Iraq!
The US found a “free” Iraq wanted that.
I don’t think any company went there to set-up a rest-of-the-world-standards network yet.
The metric system is indeed better, which is why all science in the US (at least at the college level) is done in metric. However, anyone trained in conversion factors can go back and forth very quickly.
As for Celsius vs Farenheight, F is based on Human Body Temp, not water. 0-100 F is aproximately what humans can survive in with appropriate clothing. (for instance, “it’s below freezing” isn’t a big deal, but “It’s below 0 F” is a big deal) It’s also a more precise scale, 180 degrees from freezing to boiling vs 100 degrees in Celsius. The difference between 90 degrees and 93 degrees F makes a difference. F is a better scale for people relating to it because the degrees are based on the smallest units that a human can percieve.
HOWEVER, Celsius is still better and we could just use decimal points to differentiate. Furthermore, it’s much more useful in science since it converts easier to Kelvin.
I freakin’ hate the Imperial system. Metric is so much easier, it’s all built on just one number…10.
hehe, 'round here we call it the “english” system.
Crazy Oreganos.
i have a quiz in earth science tomarrow on metrics! i better start studyign because is hould go to bed soon
yea we just call in the system we use heh
Hehe, that’s the first time I’ve been called that. 
I guess I should have said “back in Iowa, where I lived up until this month, we called it the english system” I have no idea what they call it out here.
Celcius is not that simple: you forgot to mention that it applies under specific conditions. Boil your water on Everest and you have to correct that 100 degrees.
You also said “or 36 inches to one yard, so that’s how many inches in a yard?”
so I would rate that as a mistake. Did you mean “…how many feet in a yard?” 
We need the imperial system brought back in it’s full glory. Its demise has probably contributed to, if not caused, the decline in mathematical literacy in UK schoolkids. Older people still talk in yards and know how far they mean, Kids no longer know how long a foot is… I don’t want my unicycle to go metric.
I rode 4 furlongs, three chains and a rod before I UPD’d yesterday.
I think horse racing is still imperial, furlongs and hands. Aeroplanes still fly at 35,000 feet.
(I am a bit worried about chains…there are 10 of them in a furlong…far too metric for me.)
How come degrees and angles have never gone metric? A failure of the decimal system? Or a recognition that the existing system has merit and convenience?
