Calculator Inputs and Outputs
Inputs
- Vertical rise (ft) — example: 250
- Horizontal distance (miles) — example: 2
Results
- Average grade
- Incline angle (degrees)
Formula used
Grade percent = vertical rise ÷ horizontal distance × 100.
How to Use the Incline Grade Calculator
Enter the requested values, confirm the units and assumptions, then select Calculate Incline Grade. The default inputs provide a complete working example, and the supporting outputs help you verify the primary result.
Formula
Grade percent = vertical rise ÷ horizontal distance × 100.
Understanding the Results
The primary answer appears first, followed by useful supporting values, conversions, or comparisons. Calculations retain additional internal precision before displayed values are rounded.
Accuracy Tips
- Use consistent units and measured values.
- Review whether the assumptions match your situation.
- For estimates, include realistic waste, fees, efficiency, timing, or contingency values where provided.
