America does more "stick-built" construction than some countries, since we retained more of our forests longer (old-growth forests are a vanishing breed, but we haven't yet killed off the softwoods). So it's been important for us to have standardized construction-lumber sizes... which are misleadingly land inconsistently labelled but which are still based on inches and feet.
Elsewhere things have gone somewhat differently. For example, the UK has lost almost all its woodlands, which may be part of the reason folks there are now more likely to build in brick. And they were smart enough to go metric long ago.
Hence my question: are there standard construction-lumber sizes outside the US, and what are they? Or is the US exporting enough pine that our pseudo-2x4's and 4'x8' plywood have become international standards despite the inconvenience?
(I'm explicitly neither assuming there are international standards, nor that there aren't, because I simply don't know. If this starts turning into a complicated/long list, of course it can be pulled to community wiki or wherever... but let's see if there are more than three or so sets of data before assuming that's needed.)
I guess the question I was really trying to ask was whether the metric universe had standardized a set of common off-the-shelf dimensions across countries that would serve as an equivalent of the American sizes for purposes of plan dimensions -- if an American shed is mostly 2x4's on 16" centers with 1/4" 4'x8' sheathing (some of those being real measurements and some nominal), is there a well-accepted set of metric dimensions would replace those elsewhere to build the equivalent shed, and are those subject to the same kind of inconsistency?
An answer of "almost; there are three such systems battling for dominance and they are..." or "not really, everyone has their own set of numbers influenced by their own historical construction practices" or "actually, there IS an international standard known as..." would then qualify as a clearly acceptable answer.
As I say, the real question is whether we can translate something between metric and American in any reasonable way, or if we just have to count on everyone making their own adjustments.
(Let's see, in stones/furlongs/fortnights that would be...)
