# How to Convert Angle Degrees to Slope ••• spukkato/iStock/GettyImages

An angle can represent a slope, and a slope can be measured as an angle. A slope is the measured steepness of growth or decline over a specific amount of distance. In geometry, calculation of a slope develops from a ratio of a change of y-coordinates, also known as the rise, over a change in x-coordinates, known as the run. When given the degrees of an angle representing the slope, you can calculate the slope as both a gradient with the ratio in decimal form and a percentage by employing the trigonometric tangent function.

Obtain an angle in degrees. For this example, let the angle by 40 degrees.

Calculate the tangent function of the angle with your calculator. For this example, the tangent of 40 degrees equals approximately 0.83901. This is the slope as a gradient.

Multiply the gradient by a hundred on your calculator to obtain the percentage of the slope. For this example, multiplying 0.83901 by 100 equals 83.901 percent.
