What Rise Do You Get With A 9‰ Slope Over 5 km?
Permille slope means units of rise per 1,000 units of horizontal run. Once the run is expressed in meters, the rise is a direct multiplication.
Interactive Rise Calculator
Enter slope as permille or percent, then choose a run distance to calculate rise directly.

Worked Steps
- Convert 5 km to 5,000 m
- Use rise = (permille / 1,000) × run
- Rise = (9 / 1,000) × 5,000
- Rise = 0.009 × 5,000 = 45
- So a 9‰ slope over 5 km rises 45 meters
FAQ
- What percent grade is 9‰?
0.9%. - How much rise is that per kilometer?
9 meters per kilometer. - Do I need to convert kilometers to meters first?
Yes, or use any consistent unit system. The rise and run must use matching units.
Practical Context
How this exact question appears in real work and what the result helps you decide.
Example 1: Rail And Civil Profiles
Who Asks This Question?
Rail, road, and drainage teams ask what rise a 9‰ slope gives over 5 km when checking alignment drawings and profile notes. For this exact query: What rise do you get with a 9 permille slope over 5 km?
What This Answer Tells You
The answer shows the segment rises 45 meters, which is the number needed for elevation planning and quick design checks. For this case: Rise = 45 meters.
Example 2: Field Communication
Who Asks This Question?
Survey crews ask this exact 9 permille over 5 km question when translating a gradient specification into an elevation change that is easier to discuss on site. For this exact query: What rise do you get with a 9 permille slope over 5 km?
What This Answer Tells You
Knowing the rise is 45 meters makes the gradient more concrete for layout reviews, checkpoints, and stakeholder updates. For this case: Rise = 45 meters.
