Brain fart..Scale conversion multiplier help needed

[marc_reusser]

For some reason my brain is just not functioning.....

Can somebody give me the scale conversion ratio/multiplier for full size/1:1 to 1:35  .......I seem to think and end up with .02857......but just not sure.


Marc (really losing my marbles)

... are you serious ... 

0,028571428 seems to be correct ... (as far as I can trust my pocket calculator and BRAIN 1.0)

    0,02857142857142857142857142857143   is a good approximation

Thanks guys......was just having one of those moments, when for some reason it didn't make sense to me.....and I didn't trust myself.

Marc, once you've worked it out, not sure if you may find this little applicaton as a handy tool to keep on the "desktop"...I've found it a quick and easy tool to refer too, rather than walking to the other end of the house to the hobby room to find a scale.  You are able to add which ever scale you want into it and the conversion will calculate.

Easy rule : when you have a size s on a 1:n scale model and you want to know how much it would be on a 1:m scale model, you multiply s by n and divide by m.
It works even if n = 1. So you must divise by 35 = multiply by 1/35 = what Jacq said with a veeeeery small error still less than your minimal resolution, Marc (but when you get even better, we might have to add a few digits ).

This site has a bunch of good calculators, its a button at the top right:

Paul,

thanks for that link - the bolt hole calculator is really useful (calculates any number of bolts around any size of circle)

I make Excel spreadsheets that have the conversions by the scale inch, and then have 1/4 - 1/2 - 3/4 on the top to add into the whole inch conversion. No calculator needed. I can fit 192" on one printed sheet easily, more if I made the font smaller.

Marc! You call it idiot scale! 1:32, but I say it's a whole lot easer to look at the ruler! HA LOL

The angle of the dangle is inversely proportionate to the heat of the beat ...

Hi All

Sorry for being dim but why not just divide by 35?  If something is 1000mm long in the real world it will be 28.57mm long in 1:35 scale.

I suppose I am missing a point somewhere

I'm with Jim.  A multiplyer looks like an answer you'd get if you asked an areospace engineer.   I just convert 1/1 measurement to inches and divide by whatever the scale factor is.   Or multiply the model dimension by the scale factor to get 1/1 scale.   

Here's a math question.  How do I figure the percent of enlargement or reduction to a drawing to go from one scale to another?  (I actually posed that question to an arerospace engineer friend, and the reply he sent me looked like Einstein's chalkboard after a pot of coffee-- there's got to be an easier way.)   

Math ain't my thing, fortunately its a skill that can be replaced by the $4.99 solar calculator I keep on my workbench!

I gave the answer above, Dave. To convert a plan in 1:n scale to a plan in 1:m scale, you enlarge by n/m. (If n < m, this means you reduce...)

Example : you have a plan in 1:48 scale and you want the thing in 1:64 scale. You "enlarge" by 48/64 = 0.75. That means you set the copier at 75% (and so you reduce the plan).
In the other direction, from 1:64 to 1:48, you enlarge by 64/48 = 1.33. So you set the copier at 133%.

Hope this is less difficult than general relativity...

[DaKra]

Thank you Frederic!  Crystal clear now, and I will enjoy explaining to my engineer friend, the simple way to solve this problem.
