I have searched for what I thought I found a long time ago, but can’t seem to locate it now. I want to build in scale 1:29. Is the conversion, roughly, 1foot = 1/2", and then conversion to metric is roughly .45mm?
Is this loosley the way to figure it? I am not a stickler on the exact conversion. I just want to be in the ball park. Buildings will be outside and no one is going to put a ruler on anything. 
Thanks for any feedback.

I don’t know your answer, but on the home page, under the right picture, in the “Some other site Features” block, there is a scale converter… Roughly 1/2 inch = 1 foot is 1/24th scale…
Shelley, To find the scale measurement, divide your prototype measurement by 29. For a foot, you typically want the answer in inches - so 12 inches divided by 29 = .414" inches. That’s “about” equal to 13/32 (.406") I don’t think that’s a very handy number to work with. I find it a lot easier to work in the prototype dimension. I have several different scale rulers that I use. I have a transparent one from http://thescalecard.com/ And an aluminum one from http://therailscale.com/

When I build I never try to convert any dimension - I just use the rulers to measure in the prototype dimension. Both are available for 1/29 and they go up to 2 feet long. The transparent one is flexible, so it can be used to measure around non flat surfaces. I find both very useful.
Thank you so much, that is what I was looking for.
What I’m looking to do is build a replication of the house I grew up in, in PA. I have the dimensions of the house and just needed to know how to scale it for my USA engines 1:29.
I prefer to use the metric system when measuring, so this was what I was looking for.
thanks again.
Here is a very useful converter tool that has many useful items built in to it that I use more than I thought.
It is priced very reasonable and I think it is well worth it.
Hope this helps.

I use any handy pocket calculator:
To 1/29, just divide by 29.
Inches to mm: Just multiply by 25.4.
In one operation, Inches to 1/29 to mm: Multiply by .87

(A close approximation is your metric ruler. Just read a CM as a foot.)
shelley sherbondy said:Kind of late for this party, but anyway ..... the closest "logical"** division point to that "creative" 1:29 marker would be 30 in a decimal system. Gives you funny decimal numbers, as in 10ft":30= 0.33ft = 4". Of course it is a lot easier if you look at 10ft as 120":30=4"

Sorry, have to go get a Tylenol; that fraction “magic” does it to me!
**= for those of us who started out in a normal decimal system, then added fractions for length measurements (that’s part of immigrating to NA) and still wonder why anyone would bother. 
BTW if I can find the link to the original article where Lewis Polk explains the perceived “logic” behind the 1:29 I’ll post it.
Shelly,
another simple scale answer is to go to an engineering/drafting supply store and purchase an ‘engineering scale’. It will have a scale at 1:30, which is so close to I:29 you will never see the difference.

Yes gang, I found it

Make sure you’ll have a saltshaker handy, you’ll need it!
PS BTW the only thing I would add to that write-up:
Trust me; have I got a deal for you!
As always, strictly my opinion! :lol:
