How the converter works
Angle is computed as degrees = atan(rise/run) × 180/π. Percent grade is 100 × tan(degrees). When you enter any value, the tool converts it to the other formats instantly. Use consistent units for rise/run — choose units from the dropdowns.
Typical uses
- Roof pitch conversion (slope ↔ degrees)
- Site grading and ramp design
- Cross-checking drawings and specs
