Yes.
But the original poster said 80 *degrees*. He had clearly mistaken one
for the other or heard about it from someone who'd been so mistaken.

So how did they get 0.8 from 37.5 degrees?
Is that the tangent of the slope angle? It is close numerically, but
it doesnt sound right, as it can exceed 100%. Or is the sinus? That
doesnt match numerically with 0.8.

Your observation is correct, it's the tangent function. Gradient
is the ratio of vertical elevation -vs- horisontal displacement, and
with slopes greater than 45 degrees the vertical elevation goes up
faster - hence it is possible for gradient to measure past 100% .
For instance, the gradient of a ladder leaning against a wall can be
several hundred %'s, and the gradient of an upright wall itself is as
much as infinite...

Why? We are talking about an angle of 37.5 degrees here which can be
done with most 4x4's with low range T-case. On tarmac you will even
succeed without spinning wheels.
