Code 100 is 1/10 of 1". So....

[MarkInLA]

If code 100 is in fact one tenth of an inch, what is it in inches ? IE: Is it like 5/32" or, say 11/64" ?
Put another way, how many inches is a tenth of an inch ? Would it have to be expressed in 128ths of an inch to make an exact mechanical translation ?

Code 100 railshould be 0.100" tall. Code 55 is 0.055" tall.

[Missaberoad]

Not sure if this is a trick question but wouldn't it be 1/10"?

[Chris333]

And c55 is 55/1000".

Both, the question itself, and that it was posted in the Challenges section.

Seems you've answered yourself

What?

Aaaaaaaaaand this is one of the many reasons the metric system is better.

What's wrong with 0.1" ?     I almost never use fractions in my work.

Yeah, because code 25.4 rail will stop any confusion.

If the original question was serious, and you want a common-ruler fraction, it would be 6.4/64ths.  6.5 would be fairly easy to eyeball, with a good ruler, and would probably be close enough.

There are also architect's rules, usually triangular, and marked in 10ths, 20ths, 30ths, 40ths, 50ths, and 60ths.  1/40th is exactly 4 N scale inches, and the 50ths are good for measuring Evergreen styrene strips.

Plus, you can buy 6-inch stainless steel rulers in decimal inches, and metric, along with the 64ths I use for most of my work.

In that case, we might as well just call it 13/128"

GUYS GUYS !! It was not at all meant as a joke, brain teaser, provocative, tweezy......

I was, in literal terms, asking for the correct breakdown in inches what one tenth of an inch would be, would bear....
Thus far the only persons I see who took it the intended way were nkalanga at 1:51:13 and Peteski at O1:54:40
Thanks, sirs
But thanks to all, just the same. You meant well; just mistook my direction. It's summer !!

What exactly was the purpose of that exercise?  Do you have any specific need, or reason to use fractional dimensions for code 100 track, or were you just pondering?

On the Railwire, what you saw in this thread is a typical response.  And we haven't even ventured too far off-topic (which is another thing that also frequently happens here).
