Formulas

Steigung (%) = (Höhenunterschied / Horizontale Strecke) × 100

Steigung (°) = arctan(Höhenunterschied / Horizontale Strecke)

Frequently Asked Questions

How is slope percentage calculated?

Slope percentage equals (vertical rise / horizontal distance) times 100. A 10% slope means 10 meters of rise over 100 meters of horizontal distance.

How do I convert between degrees and percent slope?

Percent equals tangent of angle in degrees times 100. Degrees equals arctangent of percent divided by 100. A 45-degree angle equals 100% slope; a 100% slope does not mean vertical.

What is the Slope and Gradient Calculator?

The gradient calculator computes the slope in percent, degrees and ratio from the height difference and horizontal distance.

How does the Slope and Gradient Calculator work?

Enter the height difference and horizontal distance. Slope in % = (height / distance) * 100. The calculator also shows the angle in degrees and the ratio (e.g. 1:10).

Key Data and Facts

Slope % = (height difference / horizontal distance) * 100. 100% slope = 45 degrees. Road construction max. approx. 12%. Roof pitch: 15-45 degrees typical.
