DenDer Posted September 2, 2008 Report Share Posted September 2, 2008 Just noticed a fault in the pcb dimensions given in the dokuwiki.http://www.midibox.org/dokuwiki/wilba_mb_6582-The base PCB is exactly 9200mil x 7215mil (9.2 inches x 7.215 inches). This fits exactly into the PT-10 case by PacTec, with mount holes that line up with the case standoffs.If i take 9.2" multiply this with 2.54 cm (1") = 23,36 cm or 233,6 mmIf i take 7.215" multiply this with 2.54 cm = 18,33 cm or 183,3 mmAm i right?

bugfight Posted September 2, 2008 Report Share Posted September 2, 2008 if a mil was a mm...and a mm was 1/100 cm... Quote Link to comment Share on other sites More sharing options...
DenDer Posted September 2, 2008 Author Report Share Posted September 2, 2008 Then what is a mil ??? A windmill? We got lots of those here.... ;) Very confusing ??? We, here in Holland, use 'normal' measures.. :PAnd isn't a mm 1/10 cm.... Quote Link to comment Share on other sites More sharing options...
Wilba Posted September 2, 2008 Report Share Posted September 2, 2008 A thou, also known as a mil, is a unit of length equal to 0.001 inches (a "milli-inch" or a "thousandth of one inch").http://en.wikipedia.org/wiki/Thou_(unit_of_length)Most PCBs are laid out in mil because standard unit of spacing is 100mil (IC pins, SIL headers, LED leads, etc.) Quote Link to comment Share on other sites More sharing options...
DenDer Posted September 2, 2008 Author Report Share Posted September 2, 2008 Okay getting it 8) US measures, European measures.....when will the world decide that a lenght is a lenght...... all this conversion is driving me mad with 200 mph which is about 320 kmph :o Quote Link to comment Share on other sites More sharing options...
SLP Posted September 2, 2008 Report Share Posted September 2, 2008 US measures, European measuresactually they are called the "metric system" (meters, kilogramms, liters, degrees Celsius, etc) and the "Imperial Units" (inch, foot, yard, mile, gallon, ounce,.. all the "weird stuff", see the those charts).note that there are only 3 countries where the metric system is not the primary or sole system of measurement:Liberia, Burma, and... damn.... I can't remember the last one. ;DI think it's the USA...Been trying for all my life but I cant add up your subtraction.Work' date=' eat, playthen go to sleep that won't get me no satisfaction.Gotta find a way out yeah a way out of this mess.So sick of trying to make my time last and ending up with less.I know your way of doing things and it has lost its attraction.Why settle for twenty-four when I can have a hundred fractions.Who knew I'd be the one pulling off the perfect crime.So heres my new line I'll change your mind and the metric system to time.Caused trouble all over town and it's bound to start a reaction.Metric time will come around it's gonna overtake your contraction I've found a way out yeah a way out of this stress.I made my time last and its total success.Got my way of doing things and its bound to gain your attraction.A hundred hours is my supply its gonna give us all satisfaction.No doubt I'd be the one pulling off the perfect crime.So here's my new line I'll change my mind and the metric system to time.edit: typo Quote Link to comment Share on other sites More sharing options...
bugfight Posted September 2, 2008 Report Share Posted September 2, 2008 maybe it would be different if kilometer were pronounced correctly... Quote Link to comment Share on other sites More sharing options...

SLP Posted September 3, 2008 Report Share Posted September 3, 2008 the big brain of SLPyeh.. it's like a huge library... with the lights turned off ;D© Stryd_one IIRC. Can't find it anymore in the MB-Quotes Database Quote Link to comment Share on other sites More sharing options...
/tilted/ Posted September 5, 2008 Report Share Posted September 5, 2008 One place where the great imperial metric thing is really getting weird is the SMD world.Some packages have imperial spacing, most have metric, and as Wil says, most thru-hole parts are imperial, too, so trying to route these using a CAD software with a specific grid gets to be "challenging" - read "irritating".Ahh, fun and games.
