1 percent slope in inches per foot

Since one foot is 12 inches a four percent slope is .04X12 = 0.48 inch drop How much is 15 percent added to five inches? The distances in length and height and the total have the same unit (e.g. To calculate the slope you divide the rise by the run. Determine the desired grade—typically 1-2% (1/8" per foot to 1/4" per foot) is enough to provide enough runoff. There are 4 different ways of that are used to specify the slope. 3 33. 2-1/2 2.25 44. Total Distance, Length and Height For every 50 inches the slope changes 1 inch. 3/4. so on and so on Example: a road with 15% slope has an angle of 8.53°. Then select a fraction if there is any. First, solve for the slope in decimal terms, bearing in mind that percent is just 100 times the original number: Percent slope = 100(rise/run); −2 = 100(rise/run); (rise/run) = −2/100 = −0.02. Slope Ratio: 3:1 or 3 to 1 Percent Slope: 33% Degree Slope: 18.4o Inches per Foot: 4 3 1 Slope. Example: What is the vertical drop of a 2 percent slope in feet over a horizontal distance of 150 feet? For example: A 12/12 roof pitch would be selected as 12 inches of rise per foot with no fraction and the value generated by the calculator would be 45º. Select output Fraction Precision, Decimal Inch or Metric mm. Adding 15 percent to a number is the same as multiplying the number by 1.15. To find the percentage multiply this decimal by 100, like this: 100 × .3125 = 31.25%. The Gradient Calculator may be another online program that may interest you. Slope Ratio: 3:1 or 3 to 1 Percent Slope: 33% Degree Slope: 18.4o Inches per Foot: 4. The percentage grade is the slope, written as a percent. 1.00 100. 0.25 400. feet or meters). Select and Re-Calculate to display. Horizontal to Vertical Slope Ratio ( __ to 1) 1/4. Enter the values for the roof pitch in inches per foot rise. 5 20 Use our angle unit conversion calculators to convert your slope from degrees to another unit of measurement. At a length of 200 feet, a height of 30 feet and a total distance of 202.24 feet is covered. For instance, if you travel 3 inches vertically and 3 feet (36 inches) horizontally, the slope would be 3:36 or 1:12. 3 foot just less than 3/4 of an inch. When the slope is decreasing, height and slope have a minus as prefix. 1/2. They are: the angle of inclination, percentage, per mille and it can also be expressed as a ratio. Calculating the Slope Percentage. 1% grade = 0.57 degrees = 1 cm per 100 cm = 1 inch per 100 inches = 0.125 inch per foot Vertical Rise, Horizontal Run and Slope Length Horizontal to slope areas - inches/feet 1 Slope. 4 25. The stake at the top of the slope is called the hinge. Author: Steve Last modified by: Steve Created Date: 4/9/2008 5:56:57 PM Other titles: Slope … Tie a string at a fixed height on the hinge. Slope percentage is calculated in much the same way as the gradient. Pound grade stakes into the ground on each end of the area you need sloped. The angle of incline can also be expressed in other units of angle measurement, such as radians or grads. 0.75 133. Fraction Precision Set 1/8 1/16 1/32 1/64 Decimal Inch Metric In your example the rise is .25 inch over a run of 12 inches so the slope is .25/12 = 0.02083333 Written as a percent this is 2.1 %. Convert the rise and run to the same units and then divide the rise by the run. 0.50 200. 1.75 57. two foot just less than 1/2 inch. This is read as a "one in twelve slope." The stake at the bottom of the slope is called the toe. Caution: The ratio is determined to be "1 in n" which is different to the mathematical "1:n". 1.50 67. 2.00 50. so for 1 foot it would be just less than 1/4 inch. 1-1/4 1-1/2 1-3/4 1.25 80.
