The beauty of the old system was that it mapped onto the everyday experience of farmers. I am sure hundredweights and furlongs and so forth all made lots of sense. But units have to cross cultures and times — the only intuitive units left to boast about are the foot and the yard, which are 30cm and roughly a meter. Indeed, we are probably taller now than when the yard was defined to the extent that the meter is proba…

Or by Wikipedia: 25.4 millimetres

There are costs to sticking with the imperial system. Non-US buyers want metric products which fit with their existing tooling. The factories of the world want all-metric manufacturing, which reduces costs. Error from unit conversion is a real problem. Designing new products in metric wouldn't require old products to be replaced with imperial. Each product line has it's own special repair kit, spare parts, already. I…

Ireland also went metric. We switched road speed limits in 2006ish, so all the signs say "km/hr" so you don't forget (it's also helpful to tell when you cross the border unto hr uk). Beer is sold in 568ml (1 pint), but milk is sold in litres.

It's quite interesting in Australia that you buy a pint of beer if it's in a glass (or a pot, which is much smaller or schooner, pronounced 'skooner', which is a bit smaller), but bottles are never sold as imperial are generally 375mL.

Fahrenheit is absolutely bizarre outside US, scaling is so arbitrary it's not funny.

Could you explain what you mean? I think my comment does a pretty good job of demonstrating that the scalig is nicely suited to the temperatures a human being experiences over the course of each year.

If you had to use decimals in Celsius for everyday measurements then you might have a point, but since you generally don't it really doesn't make a difference.

There's easily enough precision in the Celsius scale for everyday measurements, so it all comes down to what you're used to.

In an age where everyone carries a computer in their pocket, the metric system's only advantage (that it makes converting units easier) is irrelevant.

Conversions being easier is nice, but the main advantage of the metric system is that it is a set of properly standardised units that the rest of the world uses...

Having a computer in your pocket is never going to change that.

Which ones? I've never heard it.

The British press regularly measure things in football (soccer) pitches, London double-decker buses, Eiffel towers, blue whales and Wales. The Register regularly does piss-take articles about this and even provides a handy conversion calculator. http://www.theregister.co.uk/Design/page/reg-standards-conve... http://www.theregister.co.uk/2007/08/24/vulture_central_stan...

I was under the impression El Reg does it as a joke to the US.

Even though I'm an ex-physicist where nearly everything was done in metric, I'm decidedly anti-metric. Most of the metric system has no empathy for the everyday life of humans and is better suited for making scientific equations easier. It is roughly the equivalent of choosing esperanto for consistency.

I grew up in a metric country. The metric system is totally fine for everyday use. We know that 1.8m is tall, that anything below 5 celsius is cold, and that 100kg is heavy. The only downside is that some stats are only published in imperial units - fuel efficiency being the worst offender.

In my country our fuel efficiency units are litres per 100 kilometres.

And also, where I live 5 celsius is flipping freezing. Under 15 is cold!

Since our civilization seems to have moved to binary for actual computations I wonder if we will someday go back to thinking in terms of halves, quarters, eighths, etc. of some standard unit. Then people would mock the metric system for being implicitly based on the biological accident of ten fingers...

Binary notion is too cumbersome - read long to use properly. As a matter of fact e-based system would be the most efficient [1]. There was an attempt to develop 3-based (ternary) computer by the Soviets[2], ternary in theory is slightly more efficient than binary (3 being close to e) but its engineering obstacles makes it quite impractical.

Nah, it is a common habit the world over, no matter what the local official system of measurement happens to be.

I like the one suggested in the book Good Omens by Neil Gaiman and Terry Pratchett, of measuring faith in Alps.

It really isn't the point that you can learn those things. People can also learn phone numbers and SSNs but we still use names. Wouldn't everything be much easier if we just referred to each other by our unique number? Addresses are also superfluous, just lat+lon with a unit # should be sufficient. Imperial measurements and their now American counterparts are based on human experience rather than something convenient…

Take it from someone who grew up in a metric country - it makes absolutely no difference in everyday use. You are used to imperial units, so they make more sense to you. I'm not, so they feel weird, complicated and completely arbitrary. Typically I have to mentally convert to a metric measurement to have any intuition of how big or heavy something is.

In everyday use, I don't care if something is one and 3/5ths of some part of somebody's finger - I'm used to metric so it looks about 4 centimetres...

I'm not a builder, but I've never once heard any hint from my friends in construction that using millimetres has ever been a problem for them in their work, as they are used to it and the construction industry in every other country except the US is geared towards metric...

Centimeter is about 2 grids in a school "checked" notebook. Everybody know after using these notebooks fot the whole education how long exactly that is. No problems with eyeballing. I have problems eyeballing an inch (only used in 5.25 or 3.14 disk sizes and in monitors' sizes). Milimeter is close to smallest unit useful in human scale - when you try to draw 0.5 milimeter scale with a regular pen, for example, the li…

> Food stuff is bought in "dekos" (dekagrams). Where? I've lived my whole life in a metric-using country and I'm fairly sure I have literally never heard of that unit until just now... Our food here is all in grams (i.e. a 100g packet of chips, 300g steak) or kilograms (1.5 kilo bag of rice).

In Slovenia, for example, food is measured in decagrams.
