Yes, that is exactly the same, there are 10 mm in 1 cm.
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.
100mm incline needs 5 meters of track.Klaus
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).
[units can be any --- mm to furlongs];-)

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 ;-)
