I think you're mixing angle and slope as if they mean the same thing,
e.g. when you say a 45% slope is actually a 100% grade and a sheer cliff
is infinite grade.
I think you mean a 45 degree angle is actually a 100% grade (or slope) and
...
Slope is defined as rise over run; in calculus
Och! Good catch, Eli. Daft beggar I am -- my mistake once again making it
clear why I'm a theologian and not a mathematician. Grin. Thank you. I sen
demonstrate this by writing sin instead of sine. Dumb me. Dummie! Grin.
With abandon,

Brilliant, Ron! Absolutely brilliant!

Slopes in pictures so rarely show how steep it actually is. Here is a study,
using Theodolite to show the actual degree of the slope and a photo without it.
Theodolite (reveals it’s a 7˚ slope, or 12% grade):

Looks like fun (except for the cold).
What is the difference between slope and grade?

Has anyone used this?

Is it good for quickly finding approximate ... no sure if I want slopes or
grades ... of the hills I ride? (I simply want to find out how steep my
hills are. For reasons of self esteem.)
Are there better ways for
I'll let someone smarter than me delve into the details, but if you take
the degree of a slope and get it's sin you have the percent of the grade.
Since I'm (and most of us) more familiar with the % rather than the degree,
I translate it.
Yes, Theodolite is the app I used for the photo. It's
Wow, of all topics to get me to de-lurk, it's this one!
I've always naively assumed that % grade was just a fraction of 90 degrees
-- eg, a 45 degree slope would be a 50% grade.
If it is based on the sine of the angle (the ratio of vertical rise to
distance along the road) as Patrick says, then
