A two percent road grade is a grade where the road rises 2 units for every 100 units travelled.100 feet horizontal travel, will result in a two foot gain in elevation. It is a relatively shallow gradient.

for every 100 feet of road you travel, you rise 9 feet

When determining the measurement of slope on a road, the equations are for grade (gradient). The formula is grade = (rise ÷ slope length) * 100

To convert percent incline to degrees, you can use the formula: degrees = arctan(percent incline / 100). For example, if the percent incline is 20%, the calculation would be arctan(20/100) = arctan(0.2) ≈ 11.31 degrees.

No. It is Big Avenue, not Main Street.
