IFYOUCANREADTHISTHELINEBUGHASBEENFIXED-IFYOUCANTTHENWHYTHEHELLAMIDOINGTHIS?!

Many times while travelling over some of the more hairy mountain roads out
west, I've come across the following sign:

		7% GRADE AHEAD 
		TRUCKS USE LOW GEAR (or something to that effect).

Sometimes the % number is slightly higher or lower. I realize this indicates a
steep incline in the road. My question is: what the hell does "7% GRADE" mean?!
7% of what? On what ratio is this number based? I can't remember whether a
higher number means a steeper grade or just the opposite. Does anyone know what
these numbers represent? Has anyone seen an extremely high or extremely low X%?
