Scale Conversions - How??


Recommended Posts

Posted

All,

 

Please remind me how to do a scale conversion. I can't remember...

 

I have a PE part in 1/350 that I want to reproduce in 1/48.

What is the % I need to use on the copier?

 

I'm not sure how it will work out, but it will give me a starting point to scratchbuild the part I need.

 

Thanks!

Tim

Tim,

 

Drop the "1/" ...

Divide the FROM by the TO

350 / 48 = 7.29 or 729%

 

But most copiers can't do that in one jump so you have to work up in stages

Square root of 7.29 is 2.7 (270%) so scale part up by 270 then scale result up again by 270.

If copier won't do 270%, the square root of 2.7 is 1.64 (164%), so do it 4 times ...

Cool - Thanks John,

 

I had that as one of the results, but thought that 729% was too much (and I didn't think about doing the other math!)

I'll see what I can come up with on the copier now.

 

Cheers!

Tim
