5.711°
That's about the same as a steep road sign. Over a kilometer on the map that climbs about 100 meters.
What it means
How steep is that?
Percent grade is rise over horizontal run. Road signs use the same definition, so a 10% hill climbs 10 m over 100 m of map distance, not of road.
The math
How to convert % to °
Grade and angle are linked by the tangent: grade % = tan(angle) × 100, and back again angle = arctan(grade ÷ 100). A 1 in N slope is simply 100 ÷ N percent.
Example: 10 % = 5.71059 °.
