Elevation Grade Calculator

Compute grade, percent grade, and angle of elevation from rise and run. (No back-filling.)
Inputs
Tip: Use any units—rise and run are converted internally.

Step-by-step derivation
Enter rise and run to see the derivation…
References: Standard slope/grade relations: grade = rise/run; percent grade = 100×(rise/run); angle = arctan(rise/run).
