DjmUK Posted December 11, 2003 Share Posted December 11, 2003 Okay then, let's see if I can explain this really frustrating thing on my mind..! 1nm (nanometer) = 1 billionth of a meter 2nm (nanometer) = 2 billionths of a meter So, 2nm would be smaller than 1nm right? (when you go smaller, the higher the number goes). But, here's where it gets out of whack: Old CPU's = 130nm New CPU's = 90nm (smaller) Then = 60nm (even smaller) Then = 45nm (a lot more smaller) So how come those numbers go down, this is really confusing me - can someone please explain this to moi?

ABC Posted December 11, 2003 Share Posted December 11, 2003 Wel it's easy to know. Just say a nm is mm... Then wich is bigger, 6mm or 2mm? Link to comment Share on other sites More sharing options...
Ayukawa Posted December 11, 2003 Share Posted December 11, 2003 I'm sorry to tell you that 2nm is only 0.5 billionths of a meter... use a scientific calcualtor to verify this(use reciprocal function btw :) ) so there's nothing wrong with it...

Niels Posted December 11, 2003 Share Posted December 11, 2003 in your bold text you're treating the Xnm as a fraction, it is simply a measurement like a CM, the higher is larger. Link to comment Share on other sites More sharing options...
Quboid Posted December 11, 2003 Share Posted December 11, 2003 That's not quite correct - 2nm is 2 lots of 1 billionth of a meter, in the same way as 2m is 2 lots of 1 meter. 1nm (nanometer) = 1 billionth of a meter 2nm (nanometer) = 2x 1 billionth of a meter Link to comment Share on other sites More sharing options...
DjmUK Posted December 11, 2003 Author Share Posted December 11, 2003 I 'think' I follow. I never thought of it like mm instead of nm. If I'm getting this right: - 0.5nm is half the size of 1nm - 0.5nm is a quarter the size of 2nm - 130nm is bigger than 90nm Thanks guys, I knew someone out there would know :) Link to comment Share on other sites More sharing options...
DjmUK Posted December 11, 2003 Author Share Posted December 11, 2003 That's not quite correct - 2nm is 2 lots of 1 billionth of a meter, in the same way as 2m is 2 lots of 1 meter.1nm (nanometer) = 1 billionth of a meter 2nm (nanometer) = 2x 1 billionth of a meter That's another way to look at it. I had to read it through 4 times to sink in (I'm kinda' slow - especially with numbers). But now I understand, so it's like saying "2x 1 meter = 2 meters"...I gotcha :) Link to comment Share on other sites More sharing options...
YaZoR Posted December 11, 2003 Share Posted December 11, 2003 i cant believe someone actually posted this, and answered their own question in the title. lol, self ownage :laugh: Link to comment Share on other sites More sharing options...

I knew which was smaller, I just didn't know how & why it was smaller (me not all there at times) :huh: Link to comment Share on other sites More sharing options...
kivine Posted December 11, 2003 Share Posted December 11, 2003 we are not dealing with negatives here, therefore 90nm is smaller Link to comment Share on other sites More sharing options...
DjmUK Posted December 11, 2003 Author Share Posted December 11, 2003 Yeah, the negatives is where I must of got confused. The higher the negative number - the smaller it gets. The smaller the negative number - the larger it gets. The higher the positive number - the larger it gets. The smaller the positive number - the smaller it gets. But I'm glad we've got it all sorted now. Link to comment Share on other sites More sharing options...
Niels Posted December 11, 2003 Share Posted December 11, 2003 right, now we can get back to three dimensional calculus. Link to comment Share on other sites More sharing options...

Umm nope. :wacko: If 1nm is 1 billionth of a meter, then 2nm is 2 billionths of a meter, therefore it's not smaller!! Its twice as big. So..... 130nm = 0.000013cm 90nm = 0.000009cm Link to comment Share on other sites More sharing options...
DjmUK Posted December 11, 2003 Author Share Posted December 11, 2003 right, now we can get back to three dimensional calculus. haha - yeah right, I have enough problems with basic maths...let alone 3D Calculus :p Umm nope. If 1nm is 1 billionth of a meter, then 2nm is 2 billionths of a meter, therefore it's not smaller!! Its twice as big. So..... 130nm = 0.000013cm 90nm = 0.000009cm:wacko:: I see what you mean, and the smaller it gets the more zeros will be put in after the decimal point.
