Im current working on a layout with 2 mainlines with reversing loops. shelf lay out with aproximately 110 feet return. my question is does any one know a simple formula to scale in ho how many scale [xx(]feet are in an inch? and how many inches would it take to create a mile? [banghead]
A mile is 5280’, or 63,360". Divide that by your scale and there’s your answer.
A tougher question: How many “achers” is your layout? I’ve got a 10.5x15 room. How many achers is that?
Since HO is 1/87th full scale you can multiply dimensions on your layput by 87 or divide by 87 if you have prototype dimensions. Simple.
Buy a scale ruler if that is too difficult.

One ft in HO is 87 scale ft. Divide 87 by 12 to get the scale ft /inch which is 7.25.
To get the number of feet needed for an mile in HO divide 5280/87 = 60.69’
Enjoy

Otherwise known as a fistmele? 6.5"? Ok, how many “Smoots” would this be?
pcarrell,
10.5’ x 15’ = 913.5’ (HO) x 1305’ = 1,192,117.5 sq. ft. in HO
1 acre, not ‘acher’ = 43,560 sq. ft.
1,192,117.5 / 43,560 (acre) = 27.37 acres in your room.
Tex,
Fistmele and smoots are measurements of distance not area. You may be confusing fistmele with acres, since its a measurement used in relation to bows, hence the connection to archer.
Dennis
I know that! That is almost in the duh category. Any unit of distance can easily be converted to area.
No I’m not, I missread what he said to be archers - not acres (yesh now I can’t even spell it right), so I just assumed he was trying to be anachronistic and arcane. I played along.
Side note - the importance of proper spelling so people don’t have to interpret what one writes.
Side note 2 to Bergie. Please add a spell check to the forum software.
Your right, so here’s your answer:
~3.5 million sq. fistmele or 38,245.67 sq. smoots.
Yea, I’m bored.

D&RGW,
I’m in N scale, but I think I can figure this out using this formula…maybe…[%-)]
And I can’t spell either.
I know this is off topic and irrelevant, but I figured that it would take at least ten 40’ shipping containers end to end and at least two wide to house a scale prototype UP Bailey Yard North Platte.
[(-D] OK, what is the first block of 1000 numbers that do not contain a prime number?
OK, I’m lost…[%-)]
pcarrell,
10.5’ x 15’ = 1680’ (N scale) x 2400’ = 4,032,000 sq. ft.
4,032,000 / 43560 = 92.56 acres.
Or you couold have used the ratio between the scales:
160 / 87 = 1.84
Then square the ratio to convert it to area:
1.84^2 = 3.38
3.38 x 27.37 (HO acres) = 92.57 acres in N scale.
Ok boys and girls, that’s enough math for this early in the morning. We’ll pick up on the prime numbers in the afternoon.
Thanks! I was trying to figure out how you did that, but I guess it’s clear that math is not my strong suit.
It starts at 22439962446379651…I believe.

What a refreshing discussion. I thought it was about the time someone would ask how you convert inchs to feet or how you figure a grade percentage again.
Let us begin with a constant which I memorized many, many years ago.
HO is a scale 3.5 millimeters equals one foot. A millimeter is .03937 inches. 3,5 millimeters times .03937 equal .137795 inches which is the constant for an HO foot.
To find how many (HO) feet there are in one inch you need to divide 1 by this .137795 constant. There is, however, an easier way: if you have a calculator - and who of us doesn’t? - you have a key on the face of that calculator marked “1/X” - I have never encountered a recent calculator which did not have it. This is the inversion key which automatically divides 1 by the number in the register. So, insert the constant .137795 into the register and hit that “1/X” key and you will come up with 7.26 - actually it is 7.257 - in the register. That is the number of feet in one inch. If you multiply that by 12 you will come up with 87.086 and that is the number of (HO) feet in one (actual) foot which is the HO ratio. Invert that number with the “1/X” key and multiply the amount in the register by 5280 feet and you will get 60.63 which is the number of (HO) feet in one (actual) mile.
Subtract 60 and multiply the remainder by twelve which will give you 7.56; The result of all this is that you have now computed that one (HO) mile is 60 feet, 7.56 inches.
Piece of Cake!!!
Umm, Philip, shouldn’t that be “neither”?
[:D]
Is it time for my nap yet? [zzz]
CHECK PLEASE!!! [:-^]
NO! NO!! NO!!! Not a spell checker! You cannot know the many hours of enjoyment I get out of reading the syntax and spelling of some of these posts!!!
