```Paul,

In the traditional way, we specify roof slope in terms of inches to a foot,
that is why we use x:12.  But in metric, you don't need to convert units by
multiplying it with odd number, instead you only multiply or divide by 10s,
100s, or 1000s, (all multiples of 10).

So the best way to represent slope is by percentage (%). That is like
specifying one centimeter to a meter (100 cm).

What is the standard way of specifying roof slope in metric countries?  In
the US we use x:12, where x is so many inches of rise in 12 inches of run.
What is the standard in metric?
