What Rise Do You Get With A 4‰ Slope Over 2 km?
Permille slope means meters of rise per 1,000 meters of horizontal run. Once the distance is in matching units, the rise is easy to calculate.
Interactive Rise Calculator
Enter slope as permille or percent, then choose a run distance to calculate rise directly.

Worked Steps
- Convert 2 km to 2,000 m
- Use rise = (permille / 1,000) × run
- Rise = (4 / 1,000) × 2,000
- Rise = 0.004 × 2,000 = 8
- So a 4‰ slope over 2 km rises 8 meters
FAQ
- What percent grade is 4‰?
0.4%. - How much rise is that per kilometer?
4 meters per kilometer. - Do rise and run need the same unit?
Yes. Convert both to the same unit before calculating slope.
Practical Context
How this exact question appears in real work and what the result helps you decide.
Example 1: Rail And Drainage Planning
Who Asks This Question?
Civil, rail, and drainage teams ask this 4‰ over 2 km question when a design spec gives gradient in permille and the project length in kilometers. For this exact query: What rise do you get with a 4 permille slope over 2 km?
What This Answer Tells You
The answer shows the segment rises 8 meters, which is the number needed for alignment checks and profile sketches. For this case: Rise = 8 meters.
Example 2: Field Communication
Who Asks This Question?
Survey crews ask what rise a 4 permille slope gives over 2 km when translating drawing gradients into simple elevation change. For this exact query: What rise do you get with a 4 permille slope over 2 km?
What This Answer Tells You
Knowing the rise is 8 meters makes the slope easier to explain on site without switching formats. For this case: Rise = 8 meters.
