content: w00t!Gosh, I wonder... did any telecom companies ever drive by and ask, "hey, y'know, couldn't help but notice your tower there.."? A beautiful tower like that, might as well turn it into an investment eh?Tim

content: I don't think anything past iron pipes is not metric, when it comes to our central european building standards. Did I forget anything?(not trying to crate another metric/imperial war, just thinking if you could provide an example.

Just look at this table showing the common sizes and conversions:https://www.colglo.co.uk/Metric_to_Imperial_Conversion

content: Quote from: Lord of nothing on October 27, 2019, 09:23:57 pmWell so you're just going to fucking smash that Pandora's Box on the concrete, ain't ya?For those not in the know, pipe sizes are a historical mess. Imperial pipe sizes aren't even imperial!Pipe sizes are a code, not a dimension.Copper pipe sizes at least are somewhat orderly (copper pipe being a newer product I suppose?), typically being 1/8" larger o.d. than the nominal size code.Tubehowever is always net size, usually O.D.. 1/2" copper tube will fit inside 1/2" copper pipe, which itself I think can just about fit inside 1/2" iron pipe, or if not then has similar I.D.?(I'm not familiar with metric pipe, if they have the same baggage or what.)Tim

content: There are other customary dimensions, I think more common in metric as well (e.g. mechanical engineering too?), but which are actually somewhat reasonable, coming from a somewhat rational basis. Not that there can be "the" rational basis for something intrinsically arbitrary, just that it's a system that's thought out rather than evolved.So, next time you pick up a 4.7k resistor and think "why didn't they round this stupid thing to 5k?", you have Renard to thank.https://en.wikipedia.org/wiki/E_series_of_preferred_numbers(Not precisely as 4.7 comes from the E series, but Charles Renard is credited with creating one of the first standards of recommended numbers (R series).)Tim

content: Quote from: Gandalf_Sr on October 29, 2019, 12:26:50 amYou have missed the point - the idea is that those conversion tables actually use such butchered conversion factors, I know that inch is 25.4mm and not 25That's why T3sl4co1l said those numbers aren't dimensions but "code".
