Slope Percentage Calculator

Slope percentage calculator calculates the slope percentage between the run and rise.

How to Calculate Slope Percentage

To calculate the slope percentage, divide rise by run and then multiply by 100.

Slope Percentage Formula is
( Rise / Run ) x 100

Example:

For example, if the run is 10, the rise is 25, the slope percentage is calculated as:

10 / 25 x 100 = 40 %.

Percent Slope to Degrees calculator

To calculate the percent slope to a degree, divide the percent by 100 and then return the number to the inverse tangent.

Percent slope to degrees formula is:

Angle = Tan^-1(Slope Percentage / 100)

Example:

For example, if the slope percentage is 25, the percent slope to degree is calculated as:

Angle = Tan^(-1)(0.25) =14.32°
