innerdream Posted March 11, 2008 Share Posted March 11, 2008 I can't remember how to do this. I need to enlarge some prints from 1/64th inch equals a foot to 1" = 40'. Can someone help? Link to comment Share on other sites More sharing options...
AJLynn Posted March 11, 2008 Share Posted March 11, 2008 Heh. Math. Let's see here, it's 1/12:64 to 1/12:40 which is like 1:64 to 1:40 which is like 1:8 to 1:5, scaling up, so you need to scale by 8/5 or 160%. I think. Link to comment Share on other sites More sharing options...

I have done this same conversion before and I knew it was around 160%. I'll give it a whack, thanks. Link to comment Share on other sites More sharing options...
neko Posted March 11, 2008 Share Posted March 11, 2008 or just look at it as a scale factor equation 1/64" = 1/748 1/40' = 1/480 748 / 480 = 1.558 Link to comment Share on other sites More sharing options...
AJLynn Posted March 11, 2008 Share Posted March 11, 2008 It's 768, but don't multiply by the 12, just divide the 64 by 40 - the extra multiplication steps are more opportunities to make math errors. Link to comment Share on other sites More sharing options...

innerdream Posted March 16, 2008 Author Share Posted March 16, 2008 Well, it was about 162% on a xerox though that wasn't perfect - close enough for the girl I go with though. Link to comment Share on other sites More sharing options...
