How Can We Convert the US to the Metric System? 1487
thesolo asks: "Despite past efforts of the 1970s and 1980s, the United States remains one of only three countries (others are Liberia and Myanmar) that does not use the metric system. Staying with imperial measurements has only served to handicap American industry and economy. Attempts to get Americans using the Celsius scale, or putting up speed limits in kilometers per hour have been squashed dead. Not only that, but some Americans actually see metrication efforts as an assault on 'our way' of measuring. I personally deal with European scientists on a daily basis, and find our lack of common measurement to be extremely frustrating. Are we so entrenched with imperial units that we cannot get our fellow citizens to simply learn something new? What are those of us who wish to finally see America catch up to the rest of the world supposed to do? Are there any organizations that we may back, or any pro-metric legislators who we can support?"

It's generally defined as the smallest line spacing so that the descenders of one line do not collide with the ascenders of the line below. But there are many cases where this rule is violated. Consider it more like women's dress sizes rather than relating to a specific dimension.

Ok, but seriously, it is an issue of context. If you're a scientist doing scientific research, by all means, use the metric system. However, for some purposes, the metric system isn't superior.
The easiest example I can think of is temperature. I've been told by lots of people that we (I'm American) should use the Celsius for temperatures. They tell me, "It makes a lot more sense, and it's more elegant. 0 degrees is the temperature that water freezes, and 100 degrees is when it boils. Think of how nice that is. It makes so much sense for cooking and scientific experiments..."
Well, that's fine, and so I support anyone who wants to use Celsius measurements for cooking or science. However, think for a second about the Fahrenheit scale. The range of 0-100 degrees is roughly the temperature in which human being can live. The exact range that's comfortable for people depends on various things, including the specific person, clothing, wind and humidity, etc. However, somewhere 100 degrees Fahrenheit is the temperature that people need to be careful about heat-stroke, and around 0 degrees is where people are in danger of freezing to death or getting frostbite, even if they're wearing warm clothes.
So while Celsius makes sense for some scientific purposes, I think Fahrenheit is where it's at for talking about weather. Likewise, if I need to estimate the length of the room and I don't have a measuring device, do you know how I do it? I walk, one foot in front of the other, and see how many steps it takes. My feet are each just about 1 foot long, and it works pretty reliably. If you want argue that meters are better for scientific purposes, manufacturing, or even construction, then by all means do so. However, different units are more appropriate for measuring different things, so don't try to tell me that I can't use Imperial units where it makes sense.

Those are extremely popular and somewhat contrived examples to prove the superiority of the imperial system. Yet what's so special about easy division by three or by 12? When you happen to need it, that's fine, but more often than not you will find yourself having to divide by four instead: estimating the amount of material needed for the circumference of a rectangle (amount of fencing, sheetrock, etc). For division by four neither system is vastly superior.
Where the imperial system is mind-numbingly and idiotically inadequate is in day-to-day length measurements. If you have have ever done any carpentry work and encountered the endless fractional "standard" sizes such as thicknesses of 5/8" or 31/32", and then tried to add those together while holding a bunch of nails between your lips, a 2x4 in one hand and a hammer in the other, you know what I'm talking about. Yes, it is a contrived example, but not by much. Addition of lengths with fractions of differing denominators is so common in everyday life that the imperial system is pretty much untenable for that reason alone. And please spare me any erudite counter examples showing how some sophisticated fractional magic actually makes it EASIER, because no carpenter or contractor I've ever met knows and uses those--they all fudge the fractions by "gut feeling" and consider accuracy to half an inch or so "good enough".
Metric makes the life of a carpenter infinitely easier. Except for fine woodwork the millimeter is the highest accuracy you need on a construction site, and you can measure and add together lengths of centimeters and millimeters all day long in your head without any loss of accuracy or confusion. Try it sometime. Incidentally, you don't really need a unit between the meter and the centimeter. While the decimeter is not explicitly used much, implicitly people have a good feel for it. Seeing a measurement of 0.3m you don't have to perform mental gymnastics to know that it's 30cm, and people intuitively have a very good feel for the length of 10cm (about the width of a hand), so they can easily visualize fractions of a meter.

Metric is nothing special. For example, the meter is based on an erroneous measurement across France. This bad measurement was used to estimate the size of the Earth so that the meter could be claimed to have a tie to the size of the Earth. (which isn't unchanging anyway, even if it were perfectly round!) We might as well use a foot defined as the distance traveled by light in a particular amount of time, with that time amount chosen so that a foot just happens to match King George's foot.
Base 10 isn't special either. Binary is special, and trivially convertable to the more-compact hexadecimal.

This is already the case. A can of cola in the U.S. reads "12 fl. oz. (355 mL)". A bag of microwave popcorn states "1.5 oz. (42.5g)". A snack bar reads "1.59 oz (45g)". No consumer product is sold without both Imperial and metric measurements.

The thing is that the metric system is officially used everywhere. Road signs, groceries, public schools, the works. The only basis that we have for even knowing the Imperial system is our parents. I've used the metric system my entire life. I know my height and weight in feet and lbs, but couldn't tell you what it is in metric units. But I can guess fairly accurately how much something weighs in kilograms, but I'm not so good with pounds. Likewise, I'm more comfortable with measuring things in meters, rather than feet.
A rather amusing story though. I am currently living in the US, trying to get by without using the old ways. I am not always successful. But I try. Anyways, I was on the phone with my Mom the other day, and she asked how warm it was here. I googled the answer, and got it in Fahrenheit (46F). I laughed, and said she would be right at home here, and gave her the answer in Fahrenheit without doing the conversion. I was rather amazed at her response. She told me that it's been so long since she's used the Imperial system that she's forgotten it. She honestly didn't remember what 46F was.
Anyways, my point is that it doesn't matter if the older people don't use the metric system. Teach it to the young, and switch the entire country to the metric system on all official items. It will all sort itself out in time.

I'm working in Canada now. Despite the fact that their government forced metric units on them, do you realize that virtually everyone (well, immigrants from metric countries notwithstanding) continues to use Imperial units (in this case, they are Imperial units -- 4.4L/gallon, etc) in their daily life?

What's really strange is working in Mexico, where they never officially use US units. Milk is sold in galones (gallons, yup, right on the label). Talking about small measurements is quite often done in pulgadas (inches). They don't use millas (miles) in normal conversation, but they all seem to have a general sense of what they are. Yardas may be well know because of American football, and Fahrenheit makes no sense to them, but they're fairly well versed in libras (pounds).
Me? I like the metric system, and use it where it makes sense to use it. But going through the expense of wholesale conversion to the metric system makes no sense and will cause more problems than it solves. Think of the sheer amount of measurements that would have to change. There's the mundane -- 37" TV's will have to change. But what about construction materials? Plumbing? Lumber? Fasteners? What about highway sytems? Exit signs, mile markers, speed limit signs, maps, documentation? The US survey system, then? Acres, townships, counties, baseline locations, meridian locations, title and deed documents? What about food packaging? Why eliminate US measurements when metric measurements are already there?

Because the imperial system is insane. The units used are more handy for measuring or describing things in everyday life, but when it comes to doing actual calculations, you are lost. The metric system measures things in tens. The imperial system, however, uses twos, threes, fours, fives, eights, tens, twelves, fourteens and sixteens [wikipedia.org] and more. How many cubic centimetres in a litre? 1000. How many cubic inches in a gallon? 231.

I don't know where you work, but as an American scientist/engineer myself I always use metric in my professional work. Meters, kelvin, kilograms. In school (chemical engineering) we often worked with pounds and gallons since they're common in some industries, but we were thoroughly drilled in how to convert between units.
I honestly don't see the problem with using Imperial units in daily life as long as professionals use metric in their work. In many parts of the country, roads are spaced one mile apart. Converting to metric won't change that. Refrigerators are designed to hold a gallon of milk. Converting to metric would mean either misfitting jugs or odd quantity containers.
Let the public use Imperial units. They happen to be useful for human-scale measurements. Just be sure to teach students that metric is the professional system.

Of course, there's nothing wrong with using decimal gallons (I fill up my car's gas tank with decimal gallons of gasoline all the time), but using binary in SI is strongly frowned upon by BIPM.
Or are you trying to focus on the conversion between volumic and cubic-linear measurements? First off, there's little point in it since converting between two such units is hardly useful in day-to-day operations, but even if it is, you're better off using using the US gallon than the liter because it has been far more consistent: 231 cubic inches since the eighteenth century. Initially, the liter was defined as a cubic decimeter, but then somebody had the idea to define it as "one kilogram of water," and despite protestations from metric fanbois, they're not the same thing. It was eventually changed back to "cubic decimeter," but now you're left with a system where "one liter" today is non-negligibly different from "one liter" a century ago.
This is why BIPM is trying to deprecate the liter outright.
