Calculate a slope from rise, horizontal run, percentage, angle or 1:X ratio. Get all equivalent values automatically.
Calculate slope in percent, degrees and 1:X ratio from rise and horizontal distance.
Enter rise as a positive value. The result represents the slope magnitude.
Slope expresses the relationship between vertical rise and horizontal run.
To calculate it as a percentage, divide the rise by the horizontal distance and multiply by 100.
The angle is obtained using the arctangent trigonometric function.
General formula
Slope (%) = rise ÷ run × 100
Divide the vertical rise by the horizontal run and multiply the result by 100.
It means there are 10 units of vertical rise for every 100 units of horizontal run.
Calculate the arctangent of the slope percentage divided by 100.
It means there are 20 horizontal units for each unit of vertical rise.
