Slope Percentage Calculator
Convert grade slope between percentage grade (rise/run × 100), angle in degrees, and pitch ratio.
Input Parameters
Instant Real-time CalculationThe Slope Percentage Calculator is governed by Grade% = (Rise / Run) × 100 = tan(θ) × 100. It evaluates the mathematical relationship between the variables.

Slope Percentage Calculator — Frequently Asked Questions
Q1 What is a 100% slope in degrees? ▾
A 100% grade means rise equals run (e.g. 100 ft rise over 100 ft run), which corresponds to a 45-degree angle (tan(45°) = 1.0).
Q2 What is the maximum legal ADA ramp slope? ▾
1:12 slope, which equals an 8.33% grade (approx 4.76 degrees).
