How many inches per foot is a 1% slope?
Horizontal to Vertical Slope Ratio ( __ to 1) Percent Slope Degrees Slope Slope Ratio: 3:1 or 3 to 1 Percent Slope: 33% Degree Slope: 18.4o Inches per Foot: 4 3 1 Slope
Inches can have a fraction (3 1/4) or decimal (3.25 or 3,25).
The first thing to do when adding, subtraction, or doing other math with inches, feet, and other measurements is to convert all the measurements into a common unit of measure. Start by converting inch fractions into decimal. Then convert feet, centimeters, and millimeters to inches.
How many inches are there in 1 foot? There are 12 inches in 1 foot. To convert from feet to inches, multiply your figure by 12 (or divide by 0.083333333333333). Other individual length and distance converters
What is a steep slope? Steep slopes are defined by law as slopes with a vertical slope of 4.5 m or more than 30 m horizontally or a slope of 15% (Figure 1).
Slope can be calculated as a percentage which is calculated in much the same way as the gradient. Convert the rise and run to the same units and then divide the rise by the run. Multiply this number by 100 and you have the percentage slope. For instance, 3″ rise divided by 36″ run = .

1% as a decimal is 0.01 and hence the slope is 0.01. That means for a run of pipe of a certain length the rise must be 0.01 times the length. Thus for you example, since the length of the run is 80 feet which is 80 × 12 = 960 inches the rise must be 0.01 × 960 = 9.6 inches.
