    8 % grade means for every 12-and-a-half feet of run their is one foot of rise.

    10% means that for every ten feet you go forward you go up one foot. In England they would call a 10% grade a one in ten.

    A 5 % grade takes you up one foot for every 20 feet or forward travel; this would be a one in twenty.

    A one in five is what you do not want.
