Percent-Gradient to Degree Conversions

Rate of Descent during Final Approach

In order to convert a % Gradient into a degree value, use the following rule of thumb:

💡

% Gradient multiplied by 0.57

Example:

5% Gradient = 5 x 0.57 = 2.85 Degrees

In order to make the calculation a little easier, just use the factor 0.6

You can of course work out the % Gradient from a certain Angle:

4 Degree = 4 divided by 0,57 = 7% Gradient
