What Rise Do You Get With A 2% Slope Over 3 Miles?
Slope percent means rise per 100 units of horizontal run. For imperial distances, convert the run to feet and keep the rise in feet so the units stay consistent.

Worked Steps
- Convert 3 miles to feet: 3 × 5,280 = 15,840 feet
- Convert 2% slope to decimal grade: 2 / 100 = 0.02
- Use rise = grade × run
- Rise = 0.02 × 15,840 = 316.8
- So a 2% slope over 3 miles rises 316.8 feet
FAQ
- What permille is a 2% slope?
20‰. - How much rise is that per mile?
105.6 feet per mile. - Would 3% over the same 3 miles be 475.2 feet?
Yes. 0.03 × 15,840 = 475.2 feet.
Practical Context
How this exact question appears in real work and what the result helps you decide.
Example 1: Road Grade Checks
Who Asks This Question?
Road, drainage, and site-design planners ask this type of 2% over 3 miles question when turning a long-run grade into an actual elevation change. For this exact query: What rise do you get with a 2 percent slope over 3 miles?
What This Answer Tells You
The answer shows the route rises 316.8 feet, which is the number needed for profile sketches, drainage logic, and corridor planning. For this case: Rise = 316.8 feet.
Example 2: Trail And Route Planning
Who Asks This Question?
Cyclists, runners, and trail runners want to know what rise a 2% slope gives over 3 miles when comparing route difficulty and total climb. For this exact query: What rise do you get with a 2 percent slope over 3 miles?
What This Answer Tells You
Knowing the climb is 316.8 feet makes the long, gentle grade easier to compare with route summaries, elevation charts, and past events or training efforts. For this case: Rise = 316.8 feet.
