Any suggestions for HO gradient?

Since 2% = 2 per hundred, that is 1 per fifty, is accepted by most builders, just multiply your 4 inches by fifty to get 200 inches. Divide by twelve to get to feet again. Or, multiply your 100 mm by fifty to get 5000 mm, or 5 m.

Why percent of grade when one in X is so much easier?

Nope.

Because that's how prototype railroads measure their roadbed gradients. Besides, what could be easier than 1 unit of vertical displacement for every 100 units of horizontal displacement describing a 1% grade, etcetera?

The percentage system works this same way independantly of *whichever* system of measurement you're using to describe the distances involved.

Percent of grade IS "number of units(percent)" in X (100 units).

It all depends on what you're used to.

Why the hell should we do that?

I actually take offense at your suggestion: some of us (a *lot* of us, including lots of folks in the UK, a supposedly metric country) actually prefer our antiquated, flawed systems of measurement.

Hmmmph.

Luddite! :-)

Be happy with it.

The statement was 100mm equals 5 m. Not "needs".

And everybody except you realised what was meant. Pedantry and stupidity make a fierce combination.

But "Obvious" stupidity needs to be slapped down, otherwise we descend into a morass of misunderstanding.

JMHO

Selectively cutting can make stupidity of any message.

Nah, just a guy who knows the difference between a logical system and a useful one.

How about just building your scenery so that it appears that you are climbing but in reality you are running on a flat track? John

No thanks, My layout has no need for in og declines.

It is flat as a pancake.

Actually all that you've really shown is that decimal is great for calculating percentages. I can do 2%, i.e. 2/100 of an foot per foot on my engineering ruler just as easily as you can do 2 cm/meter.

Jim

Except that I don't need an engineering calculator or ruler for that ;-)
