Suppose your blueprint call for 2% slope of a certain distance, let's say, 20ft 1. Convert percetange to fraction 2. Convert the distance to feet 3. Multiply the fraction by the x amount of feet 4. Convert the outcome of step 3 to decimal 5. Multiply the outcome of step 3 by 12 (there are 12 inches in 1 foot) 2% = 2/100 20ft = 20ft 2/100 x 20/1 = 4/10 4/10 = .4 .4 x 12 = 4.8 inches (round off to 5 inches) Hope this will help. Nili
