While measuring tap to hear the spoken angle continously as the angle changes. To get the percent of a slope simply enter the Rise height of the hill and the Run width of the hill below and press Calculate Slope. To find slope divide rise by run and multiply it by 100 and for angle take tan -1 of SN.
Slope Length is the square root of Rise squared plus Run squared Angle of Inclination is the tangent of Rise devided by Run Percentage is 100 multiplied by Rise devided by Run Per Mille is 1000 multiplied by Rise devided by Run Ratio is 1.
Use slope pitch calculator to find roof pitch and run by providing rise and angle. To find slope divide rise by run and multiply it by 100 and for angle take tan -1 of SN. The run is the distance from the outside of the wall to the inside of the ridge. How do you find the percent of slope using rise over run.
