''Moved from [[Wikitravel:Travellers' pub]] by [[User:Evan|Evan]]''
So, I'd like to start a [[Wikitravel:measurements|measurements]] formatting guideline for the [[Wikitravel:manual of style|manual of style]]. The main issue, I think, is metric versus imperial measurements.
I think we're going to have to give both: "It's 15 mi. (24 km) to the next village...", but I'm wondering which should go first. Our [[Wikitravel:spelling|spelling]] guideline is to use American spelling for consistency. This suggests one of two courses: we use imperial (American) first for consistency with that, or we use metric first for fairness and just because overall it's a better system.

:I think whatever is locally used should go first, and then the alternate should be in brackets. The reason is that the local used one is likely to be the 'official' measurements for things and the other is just an approximate conversion. I also think the conversions should be soft conversions. IE if something is approximately 15miles then the soft conversion (given that we are probably talking about 15 miles +/- 2 miles 25 km is a good approximation of that). However, if something is 15.0 miles then we would call it 24.1km. The conversion should not imply a higher degree of accuracy than really exists. -- [[User:Webgeer|Webgeer]] 13:49, Sep 27, 2004 (EDT)
::Agree with you totaly, Webgeer. Driving a rented car in the USA means thinking in miles. Vice versa in the rest of the world. -- [[User:Hansm|Hansm]] 14:07, 2004 Sep 27 (EDT)
:Like Webgeer, I think the local standard is the most important. I mean, it'd be nice for us Americans to have all the French distances written in miles, but does it really do us any good? If we don't understand kilometers, we're going to be in a world of hurt reading road signs and reading the speedometer. Likewise, anyone visiting the US should plan on having a basic understanding of milage (i.e. 100km=60m, 100km/h=60mph). (Must. Resist. Urge to make fun of measurement system in which you cannot simply divide by the second prime number). -- [[User:Cjensen|Colin]] 14:15, 27 Sep 2004 (EDT)
::So, I think I suggested that ''both'' imperial and metric would be listed. The question is which comes first. I'm very, very resistent to having local rules, and I'm much more interested in global ones. Is there a reason that "15 mi. (24 km)" would be useless in [[France]]? Or that "24 km (15 mi.)" wouldn't work in the [[USA]]? I think both are perfectly usable, but I'd prefer to do one universally. --[[User:Evan|Evan]] 14:29, 27 Sep 2004 (EDT)
:::Yes, having a universal rule for which comes first is a Usability Issue. A guide should provide the Most Usable number first. Consider four cases of usage:
:::*A Eurpoean travelling in Europe and we print metric first. Reading our guides is easy and natural.
:::*A European travelling in Europe and we print miles first. Each time the traveller looks for a distance, he reads it, and then says "doh! not that number! I need the one in parenthesis!". A hardship with no purpose.
:::*A European travelling in the US, and we print miles first. While the traveller may sometimes consult the kilometers translation in parens to double check his math, he will be mostly paying attention to miles anyway. He has to deal with miles on signs, miles per hour on the speedometer, so he's getting used to this whole miles thing even though he thinks it's pretty stupid.
:::*A European travelling in the US, and we print metric first. Whenever he reads the guides, the traveller mostly pays attention to the metric and ignores the silly miles stuff. But he gets a headache from switching back and forth between the miles on his speedometer, the kilometers in the guidebook, and the milage on the road signs.
:::So yes, I would argue against even having a second distance standard in parens. But I don't care that much really. What I do really care about is that we use native-standard first. I object equally to using kilometers-first for the US articles, and using miles-first for European articles. -- [[User:Cjensen|Colin]] 17:10, 27 Sep 2004 (EDT)
:::Worse than useless. I think if you were in France and asked someone for directions, showing your printed Wikitravel France guide with miles first, you would get a serious beating -- and rightfully so! :) (And vice-versa in Rednecksville, USA.) Seriously, not putting metric first in the non-US world is a silly, awful idea. -- [[User:Paul Richter|Paul Richter]] 21:33, 27 Sep 2004 (EDT)
:Surely the compromise solution of listing '''both''' forms of measurement is the most practical.... - and ''why not'' resort to "local rules" / local usage for articles? "When in Rome....." (!) I tend to think that insisting on some 'universal' means of quoting measurements will only serve to niggle / alienate some contributors for no good purpose.... (Playing Devil's advocate: If we '''must''' select a priority 'universal' form, however, shouldn't we go for '''metric''', as the system used most overwhelmingly widely and by the vast majority of the world's population?) As someone who was raised in metric, yet still speaks / thinks of himself as being 5ft 11" in height, I say: Let's go for the compromise + local rules!

::Metric is clearly superior and should always go first. -- [[User:Mark|Mark]] 08:72, 6 Vendémiaire an 213 de la Révolution
:::To be serious though, I think this is a situation where we should sacrifice universality for usability, so I'm with Colin. Local is good for this one thing. My own experience is that when I am in Europe I think of temperature in metric, and when in the US in farenheit, but I really ''cannot'' do the conversion in my head. I know what hot and cold is.
:::I have to assume that driving speeds and distance are similar. So yes, please, let's sacrifice universality and consistency for this one thing. -- [[User:Mark|Mark]] 17:15, 27 Sep 2004 (EDT)
::::Evan, you're clearly in the minority on this one, and I will personally revert out any miles I see creep up outside the US. The traveller goes first, right? Metric is the worldwide standard, so kilometers alone shall suffice, but for the US ''X mi (Y km)'' should be used. Same goes for temperatures. And oh yes, for good measure I still object to the universal American spelling thing as well. [[User:Jpatokal|Jpatokal]] 00:21, 28 Sep 2004 (EDT)
:::Before we get too carried away with puritanical zeal over this issue, can I ask please that nobody undertake blanket reversions for miles used in ''all'' contexts outside the USA? Rather, that we use the compromise of stating both metric ''and'' imperial (if you can't be bothered finding / doing the conversion, then someone else eventually will....), with priority given to local usage? It's not as simple as all that: the UK, for example, still employs miles for road distances on road signs, road atlases, etc. (for reasons best known to themselves) and such an approach will surely create confusion and aggravation. There may be other examples of this residual usage elsewhere in the world (anyone?)..... Let's be sensible here, effect a "traveller's compromise" and quote both, with respect to "quaint local customs" (such as retaining an outmoded system of measurements for everyday usage).

:::: In menues in Canadian restaurants I often see boottled beers measured in ml and draught beer in Oz. -- [[User:Elgaard|elgaard]] 08:23, 2004 Sep 30 (EDT)
== First draft ==
So, taking into account the discussion above, I started a first draft of this document. I think I captured the consensus opinion, but please review.
One exception: some people seem to think that providing distances in miles or height in feet ''at all'' outside the US is wrong. I think that Americans traveling outside the US will be better served with converted units provided in parentheses; I don't see a good reason for omitting them.
Finally: I tried to take into account the improbable situation that a country uses neither metric nor imperial units, but I couldn't think of an example. If anyone can come up with one, it'd be appreciated.
Comments and criticisms welcome. --[[User:Evan|Evan]] 13:29, 30 Sep 2004 (EDT)
:It looks great and is easy to understand the way you've described it. -- [[User:Cjensen|Colin]] 15:20, 30 Sep 2004 (EDT)
:Good stuff. I believe that reason and practicality has prevailed. I've just made a few corrections to British usage.... I know for a fact that some European countries also retain the 'pound' in various informal ways, but this probably won't affect the average traveller, so I'll not pursue this one.... [[User:Pjamescowie|Pjamescowie]] 16:38, 30 Sep 2004 (EDT)
I added a few words on the accuracy of measurements and made some minor changes to the examples so they show accuracy appropriately. -- [[User:Huttite|Huttite]] 19:38, 2 Oct 2004 (EDT)
