What Rise Do You Get With A 12‰ Slope Over 1,500 m?
Permille slope means units of rise per 1,000 units of horizontal run. Once the run is known, the rise comes from a simple multiplication.

Worked Steps
- Use rise = (permille / 1,000) × run
- Substitute the values: (12 / 1,000) × 1,500
- 12 / 1,000 = 0.012
- 0.012 × 1,500 = 18
- So a 12‰ slope over 1,500 m rises 18 meters
FAQ
- What percent grade is 12‰?
1.2%. - How much rise is that per 100 meters?
1.2 meters of rise per 100 meters of run. - Would the rise over 3,000 meters simply double?
Yes. At the same 12‰ slope, 3,000 meters of run would give 36 meters of rise.
Practical Context
How this exact question appears in real work and what the result helps you decide.
Example 1: Rail And Road Profiles
Who Asks This Question?
Civil and transport teams ask what rise a 12‰ slope gives over 1,500 m when checking alignment notes, profiles, and grade transitions. For this exact query: What rise do you get with a 12 permille slope over 1,500 meters?
What This Answer Tells You
The answer shows the segment rises 18 meters, which is the number needed for profile checks and design reviews. For this case: Rise = 18 meters.
Example 2: Survey Handoffs
Who Asks This Question?
Survey crews ask this exact 12 permille over 1,500 m question when turning a slope label into a more concrete elevation change for field communication. For this exact query: What rise do you get with a 12 permille slope over 1,500 meters?
What This Answer Tells You
Knowing the rise is 18 meters makes the gradient easier to verify and explain during markups, staking, and handoffs. For this case: Rise = 18 meters.
