Fortunately, a friend pointed out that my inches-to-meters conversion was flawed. Some quick Googling determined that lots of people still have no idea how many inches are in a meter, even after some folks have had big problems because of conversion errors."

A lot of us brits, even those taught the metric system at work, still talk in feet and inches. Our road signs (like US ones) are all in Miles, and I don't see that changing any time soon. We buy beer and milk in pints and mostly weigh in stones and pounds and not kilos. Speed over water and air is still measured in knots, and our road speed limits are in miles per hour.

So whilst we have "adopted" the metric system we still use the "old" measurements day-to-day.

Of course there is some contention over the pint (and consequently the gallon).
An imperial pint is 20 fluid ounces (a little over half a litre). A US pint is 16 fluid ounces (under half a litre), leading to the factually incorrect US maxim "a pint's a pound the world around". I think there is a small difference in the fluid ounce as well.

It is not only factual incorrect for the british pint, it is also incorrect for the Prussian pound, which was created to help the people to mentally convert to the metric system. The american pound is about 455g, which is quite close to half a Kilogram, so the Prussian State created the Tax pound as being 500g or exactly half a Kilogram. Thus the people were able to easily estimate how much a given weight in Kilogram would weigh in their hands, by just doubling the number.

Until now you see the results in Germany: Coffee is sold mostly in 500g packets, the usual size of a piece of butter is commonly referred to as "half a pound", and nearly every baker knows what I am talking of if I ask for a "four pound bread". Interestingly the pound is used only for food, and it is only used verbal, no one would ever write it on a piece of paper.

That was the wise way to go about the conversion. Here in the U.S., they tried to do it ass-backwards. Back in the 70s or 80s, they tacked little "kph" conversions onto speed-limit signs and speedometers to help everyone get "acclimated". This just pissed off and confused everyone with extra tiny numbers, and it was applied to an area of measurement that really isn't very important to metricize. (You can't even do easy physics calculations unless you use m/s anyway.)

The net result was a backlash that delayed adoption of the metric system here by decades. Instead of the in-your-face road signs, they should have just quietly started converting smaller things over and let the old system fade away gradually.

We probably will eventually switch over, but this won't happen until after our capability to design or manufacture anything domestically has totally atrophied, and we rely on 100% metric imported goods.

Actually, the English didn't go about metrication in a good way. The evidence is that they haven't fully metricised. In Australia, we used to use the imperial system, but now, most people my age don't know how much a pint, quart, ounce, pound, mile is...

To metricise speed limits, for instance, pick a long weekend. Over the weekend, replace as many speed signs as you can. (It's a good idea to make sure everyone knows that you're doing this well in advance, of course, and as an interim measure, it's probably a good idea to have 'mph' and 'km/h' on the speed limit signs, but they're long gone by now.)

In general, get everything done as quickly as you can. (Milk bottles were apparently another overnight thing even though at the time you returned them to be refilled.)

Of course, we still have our little remnants. Many people know their height in feet and inches, though the internet seems to exaggerate this. 30 cm rulers are still common, but that's probably more because it's a convenient length, and 40 cm rules exist too. Smallish bottles of drink (fizzy or milk) are 600 mL, the closest round measurement to the imperial pint (but we also have 375 mL cans (of grog or fizzy drinks) and 1.2 L bottles (of fizzy drinks), neither of which are nicely rounded imperial measurements,* so perhaps pre-metrication doesn't hold the answer for that, either).

* A British pint is close enough to 568 mL, which is closer to 600 mL than 500 mL, but two of them is 1.13 L, which is closer to 1.1 L than 2 L, and anyway, 1.1 L is close enough to 1 L that that's probably the better metrication.

Our road signs (like US ones) are all in Miles, and I don't see that changing any time soon.

Ever noticed that road signs tend to be placed 1/3 or 2/3 of a mile before an exit?

This isn't just because they like confusing people; 1/3 of a mile is about 1/2 of a kilometer, so this will allow them to switch over to metric without having to move any signs.

The metric system (SI now) is the only official unit of measurement the US government has ever adopted. It did so way back in 1893. (1866 it became a legal unit of measure). What they didn't do though, was require it's use. So since the older imperial system was still widely in use it lived on. (Some of it anyway.. nobody knows what a stone is for example) Congress went back and required the metric system's use for all goverment purposes in 1988 (unless the infomation is for public use where it can be either).

So really we use a mix of both here. In school they teach almost entirely in metric... makes the math easier to deal with when to have to convert to smaller/larger units. Common stuff like speed limits, weight, tempature, and long distances are measured in mph/pounds/fahrenheit/miles. If you go to the store, or use any tools though it's 50/50.. so smaller units like liters/grams/centimeters I think most people know pretty well.

I couldn't agree more, after all, 2.54 is a really easy number to remember and since I'm an American living in Norway, I find that I still convert a great deal. My coversions are generally based on quick conversions.

For example, if there are 2.2lbs in a kg. Then it's easy enough to use the quick multiply by 11 rule and then multiply by two (or reverse order). So for 52kg it's easy to say that 5 + 2 = 7 so 52*11 = 572 or 52 * 1.1 = 57.2 and 57.2 * 2 = 114.4. So 52kg = 114.4lbs.

As for feet to meters. There are a few quick conversion that aren't of great precision, but accurate enough for day to day life. For example, 3m = 10ft, 1 in. = 2.54cm, 1m = 40in. Of course for precision, I would alway use the 2.54 and a calculator to derive that there are 39.37007874015748031496062992126 inches in a meter. But with the engineering work that I do, it's more typical to simply derive directly the units by converting to and from centimeters and not meters.

As for volume. I of course for quick calculation simply relate the liter to the quart since when it comes to serving drinks, there's not a great deal of difference. When I need precision, it's easy to remember the numbers I've seen on American Coca-Cola bottles my entire life. A 2 liter bottle always says 67.6 fluid ounces on it. This is my base point for conversion since I can deduce that 33.8 fl oz is 1 liter. From there it's all easy.

For temperature, that's a no brainer. 0c is freezing, 100c is boiling. 32F is freezing, 212F is boiling. So 212 - 32 = 180 and 100 - 0 = 100. Therefore it's easy to asume that 180/100 is the ration. That easily converts to 9/5. Compensate for the 32 degree shift on the farenheit side.

After living here for 5.5 years and effectively performing as a calculator for everyone that needs conversions. I can convert the systems with utter ease and simplicity. I have multiple reference points which I can use in order to estimate measures within a 5% margin or error for all human weights and heights. I also can convert distances with ease (after all 60miles = 100km. 100miles = 160km, it's all gravy from there).

So what it boils down to is that if you can get through school in any country without understanding that both systems are just REALLY REALLY simple. Then go back to school and work on it. Let's face it, there's too much stupidity on this planet. If you can remember there's 12 inches in a foot and 8 oz in a cup, then you can remember 3 points of conversion reference and derive the rest.

Oops... almost submitted without adding this to make the stinkin brits happy, first of all, ASE measurement is not imperial although it has much in common. The imperial measure has a different size for the volumetric measure. Instead of 33.8140226 U.S. fl. oz. in the imperial system has 35.1950652 fl. oz. in a liter.

Firstly the c is redundant. In proper post-Einstein physics, distance and time are the same, so a speed is simply a pure number, so:

My car tops out at about 0.000000231 (or 2.31 x 10^-7)

Now for distance, or time, we need to fix a unit of distance OR time. The most obvious fundamental unit of distance is the Planck length

It can travel about 3 x 10^38 Planck lengths on a tank of gas [ remark -- your car may need maintenance, that's not very far]

Power is energy (aka mass) per unit time, so again, we appeal to Planck and find that your car produces about 4 * 10^-48 Planck masses per Planck time.

Now we've got rid of all the silly arbitrary unit standards and defined everything in terms of the fundamental properties of the universe. Most physical constants are 1 in this model, which is a handy side benefit.

Hence: A4, the standard lettre size, measures 21.0 cm by 29.7 cm; its surface area is 1/16 square meter.

Some quick Googling determined that lots of people still have no idea how many inches are in a meter, even after some folks have had big problems because of conversion errors.

Not to put too much of a point on it, but the rest of the planet doesn't have to give a damn about how many inches there are in a meter, because they don't have inches anymore. Or stones. Or bushles. Or cubits. Or zentner. Or... This is a Yanks-only problem: even the Brits can think in meters, their problem is that they can't spell the word right.

You have two choices, my fellow American friend: Either convert to metric like the rest of the world in the 21th Century, or stop complaining.

As great as Slashdot is, this U.S. bias is getting to be a pain in the ass. It is beyond me why a simple complaint about the known problems of math education in the U.S. makes the front page.
