When a grade is referred to as 6% or 8% could anybody explain
to me what exactly that means, and how I could determine the grade of a
hill. Some time ago I stumbled onto a website where you could display
a map, and if you paused your cursor on a spot it would show the
elevation, I've spent hours trying to find that site again but haven't
been successful, anybody know of it?

rise / run = divide vertical height by horizontal distance (not road
distance). That said, on most roads, it's not that far off to divide
height by road distance. You can also find the horizontal distance by
geometry - hypotenuse (road distance) squared = sum of (each side of
triangle squared).

Besides calculations, you can use abney levels, clinometers, or some
compasses have a needle to help with this. Some people use stuff like
this with trail building to be sure the slopes of the trails aren't too
steep and there'e enough but not too much outslope. Detail is too fine
for a map.

I'll leave that for the online map geeks. But the maps I use will give
me approximate slopes directly. I can also get approximate slope from my
hrm download if I had the footpod on (trail distance, not horizontal).

6% means that for every 100 feet horizontally, it changes six feet
vertically.
So, for example, if the grade is six percent uphill, you will climb
316.8 feet.

It means you failed the course. (Math, right?)

Well, this isn't the way my father told it to me, but I'm not gonna
take the time to type that out either, so thanks, google...

A tribe of Native Americans generally referred to their woman by the
animal hide with which they made their blanket. Thus, one woman might
be known as Squaw of Buffalo Hide, while another might be known as
Squaw of Deer Hide. This tribe had a particularly large and strong
woman, with a very unique (for North America anyway) animal hide for
her blanket. This woman was known as Squaw of Hippopotamus hide, and
she was as large and powerful as the animal from which her blanket was
made.
Year after year, this woman entered the tribal wrestling tournament,
and easily defeated all challengers; male or female. As the men of the
tribe admired her strength and power, this made many of the other woman
of the tribe extremely jealous. One year, two of the squaws petitioned
the Chief to allow them to enter their sons together as a wrestling
tandem in order to wrestle Squaw of the Hippopotamus hide as a team. In
this way, they hoped to see that she would no longer be champion
wrestler of the tribe.
As the luck of the draw would have it, the two sons who were wrestling
as a tandem met the squaw in the final and championship round of the
wrestling contest. As the match began, it became clear that the squaw
had finally met an opponent that was her equal. The two sons wrestled
and struggled vigorously and were clearly on an equal footing with the
powerful squaw. Their match lasted for hours without a clear victor.
Finally the chief intervened and declared that, in the interests of the
health and safety of the wrestlers, the match was to be terminated and
that he would declare a winner.
The chief retired to his teepee and contemplated the great struggle he
had witnessed, and found it extremely difficult to decide a winner.
While the two young men had clearly outmatched the squaw, he found it
difficult to force the squaw to relinquish her tribal championship.
After all, it had taken two young men to finally provide her with a
decent match. Finally, after much deliberation, the chief came out from
his teepee, and announced his decision. He said...
"The Squaw of the Hippopotamus hide is equal to the sons of the squaws
of the other two hides"

6% is the same as 6/100 which means for every 100' run (horizontal) there is
a 6' rise (vertical). A good example of a known grade is an exterior
handicap ramp. They are typically built at a grade of 8.3% or 1 inch of
rise for every 12 inches of run.
Google Earth will show elevation under the cursor.

dang I don't know if you could try and get that low of a grade in
school anymore. I mean they count attendance for like 15% of grades
these days (the whole dumming down our kids issue).
