Slope grade percent
Express vertical rise or fall as a percentage of horizontal run.
Method and scope
Grade (%) = vertical change ÷ horizontal run × 100.
Use slope grade percent for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Vertical rise or fall — m, cm, mm, ft
- Horizontal run — m, cm, ft
SOURCE AND LIMITS
Assumptions: Horizontal run is the horizontal projection, not the sloped surface length. Rise and run use the same length units.
Limitations: Direction/sign is not reported; the answer is an absolute grade percentage.
