Calculate slope from rise and run for ramps, grade checks, line graphs, terrain notes, and everyday geometry.
Informational calculator only. Verify important outputs independently before legal, tax, medical, engineering, safety-critical, contractual, employment, or compliance use.
Enter job values, review the estimate, then use the decision hints before ordering or quoting.
slope = rise / runRise is the vertical change and run is the horizontal change.
The result can also be expressed as a ratio, percent grade, or angle in other tools.
Next: average rate of change.
This page is tuned for clean geometry checks during drafting or homework around line equation from two points.
When you need quick formula verification before copying a result into notes around point slope to slope intercept.
