Formula To Convert Roof Pitch To Degrees

Find the inverse tangent of the pitch to find the angle in degrees.

Formula to convert roof pitch to degrees.

How to convert roof pitch to degrees to find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. For example on a 7 12 roof we divide 7 by 12 to get the number 583333. The roof pitch angle greatly factors into the replacement cost of the roof. Visit this page on your phone to directly measure pitch and angles.

Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. The result is 30 255012 or 30. Most people are accustomed to mathematical degrees or possibly radians if that. A 6 rise in a 12 inch run.

Rise run rise run slope. To convert between american roofing ratios and pitch degrees follow these steps. However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement. Roof angles and rafter plumb cuts.

Divide the first part of the ratio by 12 to work out the pitch. This number is called the tangent. First convert the pitch to a slope. Bear in mind that this number is the decimal equivalent so we will have to change it to degrees minutes and seconds.

Next we ll enter inv tan 5833 and exe on our calculator. A 6 in 12 slope 26 5651 degrees and 4 97056 in 12 slope 22 5 degrees. You are not halving the angle by reducing the rise this way. To do this simply convert the rise and run as a fraction to a decimal form eg.

Enter base length to calculate rise and diagonal for current pitch angle. With a 12 in 12 slope the wall or roof rises 12 inches in a 12 inch run a 12 in 12 slope 45 one could be inclined to assume that a 6 in 12 slope would equal half of that 22 5. Set bevel gauge directly from phone or tablet screen. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.

Select inches to enter decimal inches or millimeters for metric. Directly measure roof pitch angle and calculate pitch and angle on phone or tablet. Circle 360 degrees written as 360.
