Gradient (Percent Grade) to Degrees

Angle = arctan(Gradient / 100)

A 100% grade means the rise equals the run (45°). A 10% grade is a relatively steep road.

Exemple Résolu

Convert a 10% road grade to degrees.

  1. 01Angle = arctan(10/100) = arctan(0.1)
  2. 02Angle = 5.71°
  3. 03Rise per foot of run = 0.1 x 12 = 1.2 inches

Questions Fréquentes

What does percent grade mean?

Percent grade = (rise / run) x 100. A 10% grade means 10 feet of elevation change for every 100 feet of horizontal distance.

What is a steep road gradient?

Most public roads are designed for grades under 6%. Mountain highways may reach 8-12%. The steepest public roads in the world approach 35% (about 19°).
