I want to know what these scales or grades are. I want to know what the levels of M class equal?
Is the C... aid climbing?
sorry for my ignorance-

C is hammerless aid, the larger the number the greater the possible fall distance. M is basically a drytooling grade. If I were you I would go to a local book store and buy "Freedom of the Hills," a.ka. the climbers bible. The seventh edition was just released. Stay safe and fun

A vs. C ...
These ratings refer to aid climbs. The scalke is A0 to A5 or C0 to C5. Aid refers to aid climbing in general which may use a variety of pitons, bolts or chocks. C refers to clean aid climbing, using only chocks or other which do not mar the rock.
M is used only in Australia ... M0-M8. M stands for mechanical I believe.

In reply to: M is used only in Australia ... M0-M8. M stands for mechanical I believe.
M stands for Mixed, i.e. climbs with sections of both rock and ice:

Well, actually it's a little more complicated than chalkbag says, if you consider the world outside of north america.
Yes, M can stand for mixed climbing, drytooling, bit of rock, bit of ice, that sort of thing.
But, just as vertx said, here in Australia, M grades also are used to refer to aid climbing, in the same way that A0-A5 are used in the US. There is a slow shift from M to A grades now taking place, but it has some way to go.
And yes, C is hammerless aid. The same pitch may once have had an A grade, but is now climbed using nuts and cams, not pitons. As clean climbing can be harder than hammered climbing, the grade is often correspondingly higher for the same pitch.
Also check out the Casual Rating System (CRS) for aid climbing.
Have fun...
