What Is A 15% Incline In Degrees?
Percent incline is grade, while degrees measure the slope angle directly. A grade of 15% means that over a distance of 100 units there is a rise of 15 units, 15 units per 100. Converting between them helps compare treadmill settings, roads, and trail grades measured on a per-angle basis.

Worked Steps
- Convert percent incline to grade: 15 / 100 = 0.15
- Apply the angle formula: degrees = arctan(0.15) × (180 / π)
- Result: about 8.5308°
- Check: 15% incline is also 150‰
