Understanding Slope Percentage

What is Slope Percentage?

Slope percentage, also known as grade or incline, represents the steepness of a line or surface as a percentage. It's calculated by dividing the vertical change (rise) by the horizontal change (run) and multiplying by 100.

The Formula

Slope Percentage = (Rise ÷ Run) × 100%
