Summary
Enter a slope distance and an inclination angle or gradient to instantly get the horizontal distance and vertical rise.
How it works
- Enter the slope distance — the length measured along the inclined surface.
- Choose your input mode: angle in degrees or gradient (e.g. 1:10 or 10%).
- Provide the angle or gradient value in the corresponding field.
- Click Calculate (or press Enter) to see horizontal distance, vertical rise, and additional ratios.
- Use the Reset button to clear all fields and start a new calculation.
Use cases
- Converting tape measurements taken on sloped terrain to true horizontal distances.
- Calculating road or railway grade and vertical rise over a given slope distance.
- Checking cut-and-fill volumes when the slope distance is known from field survey.
- Verifying ADA ramp compliance by converting slope distance to horizontal run and rise.
- Estimating pipe run lengths when the slope and horizontal span are given.
- Setting out construction profiles where both slope and level dimensions are needed.
- Converting GPS-derived slope distances to map (horizontal) distances.
