Yes that would be 5%, vertical rise over horizontal distance 50 mm/1000mm x100=5%.
Pavement cross slopes are measured in % (usually 2% for normal crown) and highway grades are in %. That's one benefit of our conversion, cross slopes are no longer in fractions of an inch per foot (1/4"/foot) but in easy to understand percentages.

Does it refer to % of the right angle or the horizontal distance? For instance, say an angle in the first quadrant has the horizontal distance of 1 meter and the height was say 5 cm, would this carachterize a 5% gradient angle? Thank you (anyone) in advance for this clarification. Marcus On Thu, 6 Feb 2003 13:53:49 Joseph B.
