I think it's this:
1 ft is reduce to 7/8"
or 12" is reduced to 7/8"
and 7/8" is .875"
so the reduction is 12" divided by .875" which is 13.7
so your scale is 1 : 13.7.

Jim, Devide the numerator by the denominator, and devide 12 by that
result.(7 devided by 8 = .875. Devide 12 by that result yields 13.714285,
which is the ratio you require).

Jim,
This is my understanding of scale:
7/8" scale means 7/8" = 1 foot on the prototype
3/4" scale means 3/4" = 1 foot on the prototype
1/2" scale means 1/2" = 1 foot on the prototype
If 1/2" = 1 foot then divide 12" by 1/2" and you get 24, therefore
1/2" scale is 1:24.

White metal is usually a term used to describe low melting temp alloys
containing tin, bismuth, lead, and-or zinc.

I think it is close to 1:13.1 (or thereabouts). Makes for really BIG models.
That's why they model really "small" prototypes.

What are white metal castings and what is the alloy used for them??
I know I've seen this several times in the press but can someone direct to a
formula for figuring scale ie: 7/8"scale = 1:?scale.

According to AristoCraft the voltage drop is negligably different from brass due to
their metalurgy. You can write them e-mail for a more complete discussion.
For the short runs of track most of us install, I expect no problems.
Here is the basic note I got from AristoCraft in April about their
